What file is dmg

dmg is a compressed image file on MAC, which is equivalent to the common iso file on Windows; DMG can be run and loaded directly on Mac, and can be converted to ISO on Windows PC through the command line software dmg2iso.exe document.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Use the

command to run the format: dmg2iso.exe space filename (name of the file to be converted).dmg space filename (name of the file after conversion).iso OK.

dmg2iso is a free software, but its functions are relatively limited. In some cases, the target dmg file cannot be successfully converted to iso. In this case, commercial software such as UltraISO can be used for format conversion.

At the same time, users can create dmg files with customized sizes in Programs - Common Tools - Disk Utility, which can be used to store programs, package files, or create a path with a limited capacity. You can then do whatever you want with the disk, such as burning it with TOAST. Therefore, the dmg file is equivalent to a soft USB disk in Mac.

The so-called image file is actually similar to the rar ZIP compressed package. It makes a specific series of files into a single file in a certain format to facilitate users to download and use. For example, an operating system, games, etc. Its most important feature is that it can be recognized by specific software and can be burned directly to a disc.

In fact, the image file in the usual sense can be expanded and contain more information. For example, system files, boot files, partition table information, etc., so that the image file can contain all the information of a partition or even a hard disk. In general, burning software can directly burn the content contained in supported image files to a disc. In fact, the image file is the "extract" of the disc.

The image file cannot be used directly. It needs to be decompressed by some virtual optical drive tools before it can be used. The principle of a virtual optical drive is the same as that of a physical optical drive. For example, if you buy a game disc, then add the game disc to the physical optical drive and you can play the game smoothly. What needs to be added to the virtual optical drive is an image file (iso file, equivalent to the game CD), after you mount the virtual CD-ROM drive, there will be an extra CD-ROM drive in your computer, which is the virtual CD-ROM drive. Then load the image file to complete the installation of the game. If the installation is completed, you can then load the image it requires to enter the game.

Daemon Tools is a good virtual optical drive software. You can use it to directly virtualize ISO files into optical disc files. The installation of Daemon Tools is very simple. After copying the files, the system will prompt you to install new hardware for a virtual optical drive. You need to restart to complete the installation of software and hardware. Daemon Tools can be automatically set to be self-starting. It only generates a small icon on the taskbar. Click with the left mouse button to enter the menu and select the location of the ISO file to virtualize the ISO file into a CD. In fact, there are many software for decompressing image files, such as Genie Virtual CD-ROM Drive, powerISO, etc.
