Whats with the CRC32 then?
This was something suggested several times by several people. A checksum is the “perfect” way for evaluating file differences, when dealing with alternatively named of broken files etc. There are more complex checksums out there than CRC32, but I chose it as it’s supported by default on ZIP archives etc, plus it’s nicely compact. 🙂 Please note that the CRC32 listed on my file is always for an EXE or an ADF file. So comparing the checksums of DMS archives and such against my values is an exercise in futility.
