Selling freeware is a novel concept :-)

However, if you can't find exactly what you are looking for it is not 
a big deal to write a file "chunker" and "rejoiner".  As you are 
talking about compressed data I assume you want to split on file size 
rather than line count, so you just have to decide the "chunk" size.

Splitting:
* read 'chunk' bytes from file filename.bin
* write to filename.001 (or filename.aaa if more than 1000 chunks)
* write next chunk to filename.002 (or .aab) etc. etc.

Rejoining:
* prompt for "filename.bin" (or specify on command line)
* build filename inside 3 nested loops (0 to 9 or A to Z)
* open/read that file and write to filename.bin
* keep iterating until no more files and append to filename.bin
* done!

Of course, that could be a single programme containing both functions 
but differentiated with a e.g. /J or -J switch on the commandline for 
the joining operation.

I reckon you should be able to write that in less time than it takes 
to search for exactly what you want and download/test it...
