Compressed file created by Archiver, a program for Mac OS X users that helps them create archives, compress files, and extract archives; stores a file that has been split into "chunks" of user-specified size and compressed with Bzip compression in order to reduce the file size.

To create a ZSPLIT file, drag and drop your file into the application. You can also select File → Open..., navigate to your file, and click Open. After you open your file, select "Split," and choose "ZIP" compression. Specify the chunk size you want the file split in to (KB, MB, or GB), do not check the "Checksum" box, and click "Finish." To open (combine) a ZSPLIT file, double-click the file and select "Combine." From here, you can open or export your file. NOTE: The ZSPLIT file appears as a compound extension. For example, if you split a .JPG file into 3 ZSPLIT files, the files appear as example.jpg.a.zsplit, example.jpg.b.zsplit, and example.jpg.c.zsplit.
