File type: Mac OS X Disk Image File
You're here because you have a file that has a file extension ending in .dmg. Files with the file extension .dmg can only be launched by certain applications. It's possible that .dmg files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .dmg file?

Disk image files that are stored in the DMG file format and are appended with the .dmg extension are intended as virtual disks for Mac OS X platforms. These DMG files can be mounted unto a virtual drive or directly activated to launch the Apple Disk Utility program, in order to view and use the content of these .dmg files. Some installer distributions of third party applications for Mac OS X platforms are packaged as virtual disks that are stored in the DMG format, and these virtual disks are distributed as .dmg files. Windows file compression and decompression tools like 7-Zip and PeaZip can be used in a Windows-based computer to open and view the content of these DMG files.

These include MacBook, MacBook Pro, MacBook Air, Mac Pro, Mac Mini, Xserve, and iMac.

Different applications are integrated for various uses and tasks, including typing, Web browsing, launching media player, and other typical activities a person can do with a computer. This OS can open a list of file formats from Microsoft offices (.doc,) to PDF (.pdf), photos (.jpg, .png, .gif) to audios or videos (.wav, .mpeg, .mp3) and others. It is also compatible with a variety of standard devices and peripherals like printers, scanners, cameras (webcam and digital cameras).

a word of warning

Be careful not to rename the extension on .dmg files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .dmg. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
