Freeware utility that allows you to split and recombine files in OS X.

> ...you can find often binary files that are split in parts like
> filename.mp3.001, filename.mp3.002, filename.mp3.003, etc. While it
> is possible to put these parts together using commands in the
> Terminal, not everybody is comfortable with the command line.
>
> That's why I decided to write a small utility that makes it easy to
> split large files or merge pre-split files -- all from a comfortable
> OS X interface. This simplifies the process of uploading and
> downloading split files from the Internet, as well as making it
> possible to store a large file across two or more CD-R's.

Compatibility
Architecture: PPC x86 (Intel:Mac)

Version 3.0, 2009. Code rewritten for Mac OS 10.6 "Snow Leopard" (and
10.5) - INTEL ONLY!. Program is no longer compatible with 10.4 or
earlier, due to compiler limitations. Split&Concat v3.0 is the final
released version.
Version 2.5 is a Universal Binary for 10.3.9 - 10.6.8.
Version 2.0.2 automatically checks for updates. This was rectified in
version 2.2.1 onward, to manual update checks only.
