Where to find info on .000 file format?

[MGMorden]

Ok, I've got a program called WFJoin that joins together and splits up files (naming convention, .001, .002, etc, is the same as another popular program called MasterSplitter, but it's not free). Anyways, MasterSplitter also generates a binary file whatever.000 that contains checksum information on the whole set. My program generates a similar file (though not as comprehensive) in it's own .wfj format, but I'd like to support reading the .000 files as well. Anybody have any idea where to find information on reading this file format? Splitting and joing still works between the two programs, just the error checking/file verification doesn't work. Thanks.

If you can find out what checksumming algorithm they use it should be simple to figure out. Just split a known file, look for the real file data and the rest is the checksum.

I *THINK* they're using CRC32, but I'm not sure. That's not really that helpful though, as the real data and the checksum data isn't kept in the same file. So if one splits 1 file into 10 parts, there would be .001, .002, .003, .004, .005 etc to .010, and then .000 would contain checksums for every part (1-10) as well as a checksum for the joined file. This would be soo much easier if it was just kept in plain text .
