If you have a file or folder that’s too large to easily transfer using removable storage or a network, you can use DropDMG to split it into several smaller pieces:
- Set DropDMG’s configuration to use a compressed .dmg format.
- Use the Limit segments to __ MB option to enter the maximum size for any piece.
- Drag and drop the file or folder onto DropDMG. DropDMG will create files with names such as file.dmg, file.002.dmgpart, and file.003.dmgpart.
- After you transfer all the pieces, make sure that they are in the same folder, then double-click the .dmg file to access the original file or folder.
