How To Expand Dmg Files On Mac



When changing my mac HDD to an SSD I ran into the following problem: I've created a DMG image of my old HDD which has a capacity of 320GB. The DMG file remembered and saved the capacity in the image, and the problem is my SSD is only 120GB. So the DMG can't be used if I can't decrease the capacity somehow. Mount the image by double-clicking the.dmg file, select the.dmg file (upper icon) in the left pane of disk utility, and click the Partition tab. I was then able to pull down the lower-right corner of the partition graphic to fill the entire space. This increased the size of the partition to the same size as the image file. I then clicked Apply.

Part 1: What is DMG? Why We Need to Convert DMG to ISO?

What is DMG? Why should we convert DMG to ISO file? DMG is the short form for the term Disk Image file. It refers to a file format that creates a mountable disk image that is used in Mac computers. In simpler terms, it is the digital form of the physical disc. The DMG file stores compressed software installing tools for Mac. Therefore, when you download any Mac program online, the file downloaded is likely to be a DMG file.

A DMG file comprises of a raw block of data that is encrypted in various encryption methods and compressed through multiple compression algorithms as well. If you wish to protect a DMG file, you can always apply a password.

DMG files are usable only on Mac computers and hence not compatible with Windows operating systems. If you would like disk image files in your Windows computer, you must use ISO files, which use the International Organization for Standardization file format. ISO files are perfect at mounting disk image files in any Windows operating system, especially the most recent, Windows 8 and 10.

Some people use them to emulate DVDs, CD or other disk drives virtually. An ISO file also holds the disk images of operating systems such as Linux that you can copy in the USB drive or burn into a disk. It can further send Windows software installation files online. However, a binary package with the MSI installer is used to send the files.

Unlike DMG files, ISO files are compatible with Mac operating systems. On the other hand, the ISO format lacks features like compression algorithms and encryption methods. Meanwhile, ISO is also functional in Mac. Such compatibility makes ISO files, especially for software installation, better than DMG. This means that DMG to ISO conversion is inevitable.
