Split&Concat is a small utility with the OS X interface that makes it easy for people to split large files to be uploaded, or to put together split files downloaded from the Internet.

For that reason you can find often binary files that are split in parts like filename.mp3.001, filename.mp3.002, filename.mp3.003 etcetera. It is possible to put these parts together using commands in the Terminal yet not everybody is handy with that.

Of course, you can also use this program to split or recombine files that are too large e.g. to be put on one CD.

The program will warn you if you try to process a file that contains a "resoure fork", or if you attempt to split a Mac OS X program (which in reality is a folder containing files). In these cases you are adviced to first place the file on a disk image (using Disk Copy, or Toast etc.), then compress the disk image (convert to compressed) and then split the (compressed) disk image file with Split&Concat. If you then concat the split parts of the disk image file, the resulting file will contain an exact copy of the original file.

This program cannot split files into parts that are greater than 2 Gig. This is a limitation of the Unix "split" CLI.
