Sure, there are better (and slower) algorithm than crc32, e.g. md5 or SHA1 -
but that means a complete rewrite of crcheck - and for standard integrity
checking, crc32 is sufficient!

why, there's no benefit, e.g. think about changing CD-ROM letters

Currently this is not possible with CrCheck 4.xx (having ONE crcheck.txt
file). A work around is the use of DoGlobal.exe (attached) that creates for
each directory a separate CrCheck.txt (dg cr2pgp.com).

I plan to add recursive directory walking as well as win32 long file name 
support to CrCheck 5.00
