File Extension DMG

While the majority of file extensions most people see are extensions used by Windows systems or by both Windows and Mac, the .dmg file extension is proprietary to Mac computers. Actually, it is even more narrow than that—it is for use by Mac OS X computers . Mac operating systems 9 or earlier are not compatible with and cannot open .dmg files. (Sharpened)

A .dmg file is a disk image file and opening it will create a virtual disk on your desktop. (File Info) These files can be manipulated and used to burn CDs or DVDs. The most common uses for .dmg files are distributing files over the Internet or downloading them from the Net. (File Extensions)

.Dmg files are created with Apple disk utilities and have several benefits. They utilize secure password protection to ensure security and they allow file compression. (Wikipedia) These files can be opened with Apple disk utilities or third-party software such as Roxio Toast and Dare to be Creative iArchiver. (File Info)

It should be repeated that “these files are Mac specific and are not meant to open in Windows.” (File Info) However, many people have tried and there are third-party software programs such as Acute TransMac which can transfer images to Windows PCs. (Sharpened) Another option that can be used is the command line utility “dmg2img” which converts .dmg files to iso images for Windows. (Wikipedia)

Some users have reported problems in trying to open .dmg files. This can be caused by the PC not recognizing .dmg files and trying to download them to your browser window. The simplest way to fix this is to find a command such as “save link as” and choose “file”. You may also want to consider using a download manager which can be found free on the Internet.

Another common problem experienced by users trying to download a .dmg file is receiving a “corrupted file” message. While this may be true in some cases, this message can also be displayed when the file cannot be decoded by your OS. Some .dmg files use a compression type, such as bzip2, that may be incompatible with your system. For example, the bzip2 compression format can only be decoded and opened by Mac OS X 10.4 and above.
