AI files can be opened with Adobe Illustrator, Adobe Acrobat DC, PaintShop Pro, and CorelDraw Graphics tools.
An AIFC file is a compressed .AIFF file commonly used by media players and gaming consoles to store sounds. It is saved in the Audio Interchange File Format (AIFF) and compressed with one of several codecs, such as ULAW, ALAW, or G722 compression.
The AIFF (Audio Interchange File Format) is an uncompressed audio file format developed by Apple in 1998, but is based on EA IFF 85 (Standard for Interchange Format Files developed by Electronic Arts), a wrapper format used on Amiga systems. This file format comes up with a standard for storing sampled sounds. The format is good enough in flexibility, and enables the storage of monaural or multichannel sampled sounds at various sample rates and sample widths. Since the AIFF files are uncompressed, this thing making them bigger in size than other lossy formats such as MP3. These files consist of 2 channels of uncompressed stereo audio with 16 bits sample size, recorded at 44.1 khz. Because of high quality of audio, a 5 minute audio can take upto 50MB disk space which is similar to WAV file format.
The file with .amr extension is an audio data format relevant to Adaptive Multi-Rate audio codec; consists of a multi-rate narrowband speech codec which encodes narrowband signals at 4.75-12.2 kbit/s bit rate with toll quality speech starting at 7.4 kbit/s; uses link adaptation to select from one of eight different bit rates based.
The APE file is an audio file compressed with Monkey’s Audio; an algorithm for lossless audio data compression. Unlike lossy compression methods such as AAC, MP3, Vorbis, and Opus, this typical algorithm does not scrap any data during the process of encoding. The files encoded to Monkey’s Audio are usually reduced to about half of their original size. These files contain error detection and tag support that save data about the audio files. This file format is more widely used among Microsoft Windows users. It uses highly insistent compression rate and the other great thing is that the Monkey’s Audio files can be always decompressed to the exact, original files. The Monkey’s Audio encoder is freely available and can be included easily into other software programs. If Monkey’s Audio is Compared to ALAC, FLAC, or WavPack, it is relatively slow to encode or decode files.
An ARW file is a digital photograph captured by various Sony digital cameras, such as the a6300 and a7R III. It contains raw, uncompressed image data captured by the camera's CCD and saved in the Sony Alpha Raw (ARW) format based on the TIFF specification.
A file with .asf extension is a multimedia file format for storing and playing digital media streams over the network. It is a container file format that can have both video and audio content for streaming online. You will rarely find ASF files, and more probably come across the Windows Media Audio (WMA) and Windows Media Video (WMV) files that both specify ASF files having content encoded with respective codecs. Windows media files can be created and read using the Windows Media Format SDK.
The AVI file format is an Audio Video multimedia container file format that was introduced by Microsoft. It holds the audio and video data created and compressed using several codecs (Coders/Decoders) such as XVid and DivX. Since different codecs can be used to encode the AVI contents, the retrieving applications i.e. AVI players, should be able to open these only if they have the required codecs installed with which the AVI contents were created. The format is supported by default on all Microsoft Windows platforms as well as on almost all other major platforms. Several applications and APIs provide the capability to create/save, read and convert AVI to other popular formats such as MP4, MOV, WMV, etc.
AZW is a digital ebook file format developed by Amazon for its Kindle devices.

Uncompressed and unprocessed Camera RAW image file from a Canon digital camera; based on the Camera Image File Format (CIFF), a standardized format developed for saving images.
Files with .csv (Comma Separated Values) extension represent plain text files that contain records of data with comma separated values. Each line in a CSV file is a new record from the set of records contained in the file. Such files are generated when data transfer is intended from one storage system to another. Since all applications can recognize records separated by comma, import of such data files to database is done very conveniently. Almost all spreadsheet applications such as Microsoft Excel or OpenOffice Calc can import CSV without much effort. Data imported from such files is arranged in cells of a spreadsheet for representation to user.
DjVu, pronounced as “déjà vu”, is a graphics file format intended for scanned documents and books especially those which contain the combination of text, drawings, images and photographs. It was developed by AT&T Labs. It uses multiple techniques like image layer separation of text and background images, progressive loading, arithmetic coding and lossy compression for bitonal images. Since DJVU file can contain compressed yet high-quality colour images, photographs, text, and drawings and can be saved in less space therefore, it’s used on web as eBooks, manuals, newspapers, ancient documents, etc.
DNG is a digital camera image format used for the storage of raw files. It has been developed by Adobe in September 2004. It was basically developed for digital photography. DNG is an extension of TIFF/EP standard format and uses metadata significantly. In order to manipulate raw data from digital cameras with the ease of flexibility and artistic control, photographers opt camera raw files. JPEG and TIFF formats store images that are processed by the camera, therefore, not much room for alteration is available in such formats.
Files with .doc extension represent documents generated by Microsoft Word or other word processing documents in binary file format. The extension was initially used for plain text documentation on several different operating systems. It can contain several different types of data such as images, formatted as well as plain text, graphs, charts, embedded objects, links, pages, page formatting, print settings and a lot others. The format was popular for all sorts of documentation due to the variety of options it offers to users for writing manuals, proposals, specifications, resumes, articles or any similar documents. The updated version of DOC is DOCX which is based on Office OpenXML whose specifications are openly available.
DOCX is a well-known format for Microsoft Word documents. Introduced from 2007 with the release of Microsoft Office 2007, the structure of this new Document format was changed from plain binary to a combination of XML and binary files. Docx files can be opened with Word 2007 and lateral versions but not with the earlier versions of MS Word which support DOC file extensions.
Files with DWG extension represent proprietary binary files used for containing 2D and 3D design data. Like DXF, which are ASCII files, DWG represent the binary file format for CAD (Computer Aided Design) drawings. It contains vector image and metadata for representation of contents of CAD files. There are free viewers available for viewing DWG files on Windows Operating System such as the Autodesk’s free DWG TrueView. There are other third party applications as well that support reaching DWG files. DWG files contain user created information and includes:
DXF, Drawing Interchange Format, or Drawing Exchange Format, is a tagged data representation of AutoCAD drawing file. Each element in the file has a prefix integer number called a group code. This group code actually represents the element that follows and indicates the meaning of a data element for a given object type. DXF makes it possible to represent almost all user-specified information in a drawing file.
Enhanced metafile format (EMF) stores graphical images device-independently. Metafiles of EMF comprises of variable-length records in chronological order that can render the stored image after parsing on any output device. These variable-length records can be definitions of enclosed objects, commands for drawing, and graphics properties critical to render the image accurately. When a device opens an EMF metafile using its own graphics environment, the proportions, dimensions, colors and other graphic properties of original image remains same regardless of the opening device platform.
EML file format represents email messages saved using Outlook and other relevant applications. Almost all emailing clients support this file format for its compliance with RFC-822 Internet Message Format Standard. Microsoft Outlook is the default software for opening EML message types. EML files can be used for saving to disc as well as sending out to recipients using communication protocols.
A .eps file is an image file that is saved to disc in Encapsulated Postscript file format. It may contain any combination of text, graphics and images. EPS files may also include a bitmap preview image encapsulated inside for display by applications that can open such files.
Files with .epub extension are an e-book file format that provide a standard digital publication format for publishers and consumers. The format has been so common by now that it is supported by many e-readers and software applications. For example, on Mac OS, the pre-installed Books software provides the support for opening such files. In addition, there are a lot of compatible software available for smartphones, tablets and computers. EPUB file standards are maintained by the International Digital Publishing Forum (IDPF). The version EPUB 3 is also endorsed by the Book Industry Study Group (BISG), a leading book trade association for standardized best practices, research, information and events, for packaging of content.
The ERF file format is the RAW image format used by Epson cameras. Many photographers like to take their photos in RAW mode as this allows them to control the creative editing of an image and they can play around with the various settings around colour correction and white balance before they decide to convert to a more mainstream format.
F4V (Flash MP4 Video File) is a video file saved with the .f4v extension. It is based on the ISO base media file format (MPEG-4 Part 12). It is very similar to MP4 which is why it is also referred to as the Flash MP4 informally. FLV had limitations when streaming H.264/ACC contents which resulted in Adobe Systems creating the new F4V format. Flash Player can play F4V files since the release of Flash Player 9 Update 3.
Files with .fb2 extension are FictionBook 2.0 eBook files that contains the structure of the eBook. It is based on XML format and contains special tags for describing each element of the book. It was developed primarily for fictional writings and literature, but is not limited to these only. The format accommodates all the metadata as well as content in itself and allows flexibility for a number of operations such as automatic processing, indexing, and conversion to other formats. In short, it focuses on describing the structure of the file instead of specifying its appearance. Several applications as well as APIs are available to convert FB2 to several other formats on Windows, MacOS, and Linux.
FLAC(Free Lossless Audio Codec) is a lossless compression audio coding format developed by Xiph.Org Foundation. FLAC is a royalty-free open format that is saved with the .flac extension. Digital audio compressed using the FLAC algorithm is typically reduced to 50 to 70 percent in size. FLAC files can be decompressed to an identical copy of the original audio files.
FLV (Flash Video) is a container file format with the .flv extension. FLV is used to deliver audio/video content over the internet by using the Adobe Flash Player or Adobe Air. The data in FLV files are encoded in the same way as SWF files. The direct support was added to Flash Player 7 in 2003. Adobe systems created F4V in 2007 due to the restrictions of FLV.
A GIF or Graphical Interchange Format is a type of highly compressed image. Owned by Unisys, GIF uses the LZW compression algorithm that does not degrade the image quality. For each image GIF typically allow up to 8 bits per pixel and up to 256 colours are allowed across the image. In contrast to a JPEG image, which can display up to 16 million colours and fairly touches the limits of the human eye. Back when the internet emerged, GIFs remained the best choice because they required low bandwidth and compatible for the graphics that consume solid areas of colour. An animated GIF combines numerous images or frames into a single file and displays them in a sequence to generate an animated clip or a short video. The colour limitations are up to 256 for each frame and are likely to be the least suitable for reproducing other images and photographs with colour gradient.
Video format used by Google Video Player, a video playback program developed by Google; similar to an .AVI file and encoded in DivX4 with an MP3 compressed audio track; can also be played by VLC if the file does not incorporate DRM encryption.
Temporary video file generated by video ripping and conversion programs, such as StaxRip and RipBot264; contains extracted video data that can be repurposed and encoded into other video formats; typically stored with MPEG-4/H.264 encoding.
An HEIC file is a High-Efficiency Container Image file format that can store multiple images as a collection in a single file. The format was adopted by Apple as variant of the HEIF with the launch of iOS 11. It was adopted as the default file format for storing images in compressed form on mobile devices. HEIC, like HEIF, are compressed using the High Efficiency Video Coding (HEVC) standard and are smaller in size without compromising the quality.
HTML (Hyper Text Markup Language) is the extension for web pages created for display in browsers. Known as language of the web, HTML has evolved with requirements of new information requirements to be displayed as part of web pages.
An ICO file contains an icon, which is typically used to represent a Windows program, file, or folder. It stores one or more images in various sizes so they can be appropriately scaled depending on their use. ICO files are similar to .CUR files, which are also used in Windows, and .ICNS files, which are used in macOS.

The LIT file format consists of a Microsoft ITOL/ITLS HTML Help 2.0 file, which gives all sorts of amazing features like LZX compression, the binary representation of markup material, and arbitrary optional auxiliary data associated with each stream. Book text is an arbitrary number of OEBPS 1.0 markup streams and a subset of OEBPS 1.0 CSS. Images are GIF, JPEG, and PNG.
A file with .lrf extension is a Broad Band eBook (BBeB)file that contains data for a Sony BBeB, including text, images and pagination data. The file is saved in a compressed binary format which contains a header, a specified number of objects, and an object index. LRF and LRX files enclose the two BBeB book formats available. The LRF files are not encrypted and can be compiled from LRX files. The LRF files can be converted from several other file types including PDF and HTML. If your computer cannot open the LRF file, then you probably do not have the software installed to open or edit the LRF files. Programs that can open LRF files are Caliber, BookDesigner, Makelrf and Canon Book Creator for Windows, Caliber for Linux, Caliber, and Sony Reader for Macintosh.
A file with .lzh and .lha extension usually relates to archive compression file format. This file format is the same as other file compression formats like ZIP, RAR, etc. The main purpose of these file formats is to reduce the size of the format for easily sending as well as to keep them together in compressed form. AS compare to other western companies LZH files are very popular in Japan and usually used for compressing video game data. The LZH add-on for Windows 7 is built into the Japanese version of Windows 7. Microsoft first released the Microsoft Compressed (LZH) Folder Add-on for the Japanese version of Windows XP. This file format is implemented with compression provisions and features used by the Lempel-Ziv and Haruyasu algorithm
An M2TS file contain the high definition video on Blu-ray Disc and AVCHD. This file format is based on the MPEG-2 transport stream container and used for multiplexing audio, video and other streams. M2TS files can be played on the devices supporting playback of AVCHD, such as, Sony PlayStation 3s, Sony Bravia TVs, Western Digital WDTVs, Xtreamer media player, Amkette FlashTV HD Media Player and Panasonic Viera TVs supporting AVCHD.
The M4A file format is an audio file created by using the AAC (Advanced Audio Coding) which is known as a lossy compression. The word M4A abbreviated as MPEG 4 Audio. These audio files usually have .m4a file extension. This is especially true of un-protected content. It may store various types of audio content, such as audiobooks, songs and podcasts. M4A is usually realized as more advanced format than MP3, which had not been typically designed for audio only. It is just an audio layer in MPEG 1 or 2 video files. M4A format is encrypted by FairPlay Digital Rights Management as were sold via the iTunes Store use the .m4p extension. The Apple iPhones use MPEG-4 audio for their ringtones but those audio files use the .m4r extension.
The file with .m4b extension is an audiobook generally used by Apple books and iTunes. The Audio used in this format is stored in MPEG-4 and compressed by using AAC encoding. An M4B file is very similar to M4A but having support the audiobook related features, such as bookmarking and chapter breaks. The M4B files are available in both DRM enabled and DRM free versions. DRM encryted audiobooks are usually paid audiobooks from iTunes Store. Whereas, DRM free can be found easily over the internet.
An M4R file contains a custom iPhone ringtone created with Apple iTunes, a media player bundled with Apple devices. It can only be created from a song purchased from the iTunes music store that allows ringtone creation. M4R files are automatically transferred to an iPhone when the phone is synced with the computer using Apple iTunes.
M4V file format, developed by Apple, is a video container optionally protected with Digital Rights Management (DRM) copy protection to protect privacy or copy. Videos and audio tracks are wrapped around by container files to indexing and organizing playback streams. In addition, containers also provide the feature of chapters similar to those on DVDs. Apple uses M4V to encode videos in its iTunes Store. It protects unauthorized reproduction through Apple’s FairPlay copy protection by allowing M4V files to be played on only authorized computers having the accounts used to purchase the video. However, if DRM-protection is removed from M4V files, these files can be played in other video players by changing the extension from .m4v to .mp4, which is why M4V files are associated with MPEG-4. M4V uses H.264 for video and AAC and Dolby Digital for audio encoding and decoding.
An MDI file is a document saved in a high-resolution, tag-based graphics format developed from the TIFF format. It is created by Microsoft Office to save scanned documents and may be turned into a Word (.DOC) document using OCR (optical character recognition) software.
Camera RAW image captured by a Mamiya digital camera; stores the image as it was captured by the camera's CCD; usually stored on a memory card and then transferred to the computer for editing and publishing.
A file having .MID or.MIDI file extension is the Musical Instrument Digital (MID) Interface file. It is the difference from ordinary audio files such as WAVs or MP3s in that it doesn’t carry the actual audio content; hence, is quite smaller in size. The content includes the notes played, their timing, duration, and desired loudness for each note. The MID file fundamentally consists of information explaining how should the sound be heard when linked with the playback device or loaded into a specific software that interprets audio data. This makes it an ideal tool for sharing musical data between compatible apps and over a low-bandwidth connection. The smaller size enables easy storage for which even floppy disks can be used.
MKV (Matroska Video) is a multimedia container similar to MOV and AVI format but it supports more than one audio and subtitle track in the same file. An MKV file is the Matroska multimedia container format used for video. MKV is based on Extensible Binary Meta Language and it supports several video and audio compression formats. The major difference between MKV and other video formats is that MKV is a container and not a codec. MKV files are saved with the .mkv file extension. MKV can incorporate audio, video, and subtitles in a single file even if those elements use different types of encoding. For example, you could have an MKV file that contains H.264 video and MP3 or AAC for audio. MKV also supports descriptions, ratings, cover art, and even chapter points. There are several key features that MKV is future-proof. These features include:
The MOBI file format is one of the most widely used ebook file formats. The format is an enhancement to the old OEB (Open Ebook Format) format and was used as the proprietary format for Mobipocket Reader. Like EPUB, it is supported by almost all modern e-readers specifically by mobile devices with low bandwidth. The format can be converted to several other formats such as PDF, EPUB, and several other formats using publicly available software applications such as the Kindle app. There are several companies that offer free MOBI books such as Project Gutenberg, Feedbooks, and Open Library.
A file with .mod extension is a music module file created by using the standard music module format, which is based on the Amiga module format developed by Karsten Obarski and released with the Ultimate Soundtracker software for the Commodore Amiga system. Similar to a MIDI file, it consists of note patterns and sound samples, representing different instruments that are played back according to the notes. MOD files are particularly used in video games as background music and in the demoscene computer art subculture.
A MOV file is a video file type, developed by Apple Inc., that contains one or more tracks. Each track stores a movie, audio, movie clips, and subtitles. It is a multimedia container that can store different type of media elements. MOV video format is compatible with both Windows and Macintosh systems. It uses MPEG-4 coded for compression and tracks are maintained in objects called atoms which are placed in a hierarchical data structure.
Files with .mp3 extension are digitally encoded file formats for audio files that are formally based on the MPEG-1 Audio Layer III or MPEG-2 Audio Layer III. It was developed by the Moving Picture Experts Group (MPEG) that uses Layer 3 audio compression. Compression achieved by MP3 file format is 1/10th the size of .WAV or .AIF files. The format gives advantages of streaming such audio files over the internet for listening online that was previously not possible due to the large file sizes of audio files. Sound quality of an MP3 audio file can be controlled by parameter settings such as bit rate, sample rate, joint or normal stereo.
MP4(short for MPEG-4 Part 14) is a file format based on ISO/IEC 14496-12:2004 that is based on QuickTime File Format but formally specifies support for Initial Object Descriptors (IOD) and other MPEG features. It is mostly used to store video and audio but can also be used to store subtitles and still images. MP4 files are stored with the .mp4 extension. MP4 is an international audio-visual coding standard. Similar to most modern container formats, MP4 supports streaming over the internet. Due to the high compression used in MP4, the resultant files are smaller in size with almost all the original quality retained.
The file with a .mpg extension belongs to the group of file extensions for MPEG-1 or MPEG-2 audio and video compression. MPEG-1 Part 2 video is not easily available, and this extension (MPG file format) typically points to a MPEG program stream which is defined in MPEG-1 and MPEG-2, or an MPEG transport stream which is defined in MPEG-2. Other extensions such as .m2ts also exist specifying the accurate container, in this case, MPEG-2 TS, but this has little pertinence to MPEG-1 media. The .mp3 is the most common extension for files containing MP3 audio. An MP3 file is a typical stream of raw audio; the traditional way to tag MP3 files is by writing stream data to “garbage” segments of each frame, which save the media information but are discarded by the mpg file player. This is a similar technique used to tag the AAC files, but less supported nowadays.
A file with a .mpp extension is a Microsoft Project data file that stores information related to project management in an integrated manner.

WMA files are primarily used for streaming over the web similar to .mp3 files.
Files with WMF extension represent Microsoft Windows Metafile (WMF) for storing vector as well as bitmap-format images data. To be more accurate, WMF belongs to the vector file format category of Graphics file formats that is device independent. Windows Graphical Device Interface (GDI) uses the functions stored in a WMF file to display an image on the screen. A more enhanced version of WMF, known as Enhanced Meta Files (EMF), was published later that makes the format more feature rich. Practically, WMF are similar to SVG.
The Advanced Systems Format (ASF) is a digital multimedia container designed primarily for storing and transmitting media streams. Microsoft Windows Media Video (WMV) is the compressed video format and Microsoft Windows Media Audio (WMA) is the compressed audio format along with additional metadata in the ASF container developed by Microsoft. Once the WMV or WMA files are encoded with Windows Media Video and Windows Media Audio codecs then they are represented with .asf extension. WMV compresses large files for a better transmission rate over a network while maintaining the quality of the video. WMV is specifically designed to run on all Windows devices. After the standardization by the Society of Motion Picture and Television Engineers (SMPTE), WMV is now considered to be an open standard format.
