Hi,

Paul, you are thinking of install.dat. =) checksums.dat is a created by our auto installer. It is a checksum of every file that is installed. This way, when you do an upgrade, the installer checks to see if you have modified the file since it was installed, and if so, creates a .bak version of the file so you can compare your changes with the new file.

Cheers,

Alex
