Disk images pack entire folders or disks into a single compressed file, either for transport across the Internet or simply for backup. They are Apple’s preferred format for distributing Mac software and the only archive format whose contents you can directly access in the Mac Finder—no third-party software required.
|Just drag and drop a file or folder, and DropDMG automatically figures out what to do: create a disk image, convert to another format, join files, etc.||Deliver your Mac application with a localized software license agreement, a Retina-optimized background picture and precise icon layout with a link to the Applications folder, and a custom volume icon.|
|Configurations let you reuse common collections of settings, and temporary options let you easily make one-off changes.||Supports all the major formats, including compressed .dmg files (smaller than Disk Utility’s), the new LZFSE format, .sparsebundle files, .zip and .tar.gz archives, and hybrid disk images.|
|Assign a password and create mini vaults, encrypted disk images that are more flexible than FileVault and secure your files with 128-bit or 256-bit AES encryption. Compact sparse disk images to reclaim unused space.||Make backups and archives, encrypt them for safe off-site storage, and verify them to ensure that the media is still intact and that you’ll be able to restore them if needed.|
|Quickly burn files, folders, or disk images to CD, DVD, or Blu-ray. Burn OS X installer DVDs. Multi-session support lets you add files to an existing CD.||Create a device image clone of an entire hard drive, optimized for restoring using Apple Software Restore or Disk Utility.|
|Optimized for multi-core processors and runs multiple operations simultaneously, so you can keep working while DropDMG processes in the background.||Copy CDs and DVDs. Split large files or folders into multiple segments to burn them to disc or transfer them over a network.|
|Keeps a detailed log of successful operations, as well as any errors, along with throughput and compression statistics.||Automate DropDMG via AppleScript, Automator, or the command line.|
|Mount disk images as folders at specific locations in the filesystem, so that your applications can keep their support files encrypted.||For more information, please see the feature list, screenshots, or the extensive user manual.|
