Pros
Yeah, it split files. Sure.
Cons
...But does it check the integrity of the file when joining? No. So what happens when you upload a 10GB file to an unreliable file hosting server? You get downloaders crying "NOOOO" and pulling out their hair, is what. And the best part is they can't report to you which split file has the download error. Have you seen the movie The Fly? It can be off by just 1 byte, and your whole file is crappola. Be safe. Use RAR.

This review was originally posted on VersionTracker.com. a GUI PAR2 creation tool but it really does need an option to set the block size so it can be tailored to match the posting part size on Usenet. Until that happens it's still par2cmdline for me.
Thanx Loek!

This review was originally posted on VersionTracker.com. Split&Cancat have helped me alot the last year. The application works like a charm every time. So simple and easy. - I like apps who do their tasks without any 10mb of user-interface, just plain efficiency.

Developer’s Description

Split & recombine large files; create PAR files.

Utility to split or recombine large files (for use with internet newsgroups or if your file is too large to put on one CD). In Internet newsgroups large files often are split into smaller parts since messages can not be of more than a certain size to be able to post them in newsgroups. 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. That is why I decided to create 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. You can also use it to divide very large files over several CD's.The program functions also as post-processor for MacPAR DeLuxe. Starting with vs. 2.0 you can also use the program to create Par2 or Par archive files (sponsors only).
