For curating and de-duping purposes, how would one go about comparing a series of files on 2 .DSK images?


For example:


DiskA.dsk has 5 files and DiskB.dsk has 5 files, same names, same filesizes.


What would be the best way to compare those 5 files and be sure they're the same? Copy II+ in an emulator? Extract via Ciderpress and then compare in Windows checksum? It'd be nice if CP had a checksum feature, but it does not.


Any other ideas that would be more efficient and faster? Less tedious?

Sounds like the need for a Modern PC Utility that can Read a Disk Image, and Follow the Individual Files on them and do Compares and Checksums on them. besides the Whole Disk...

Yes. I have several modern tools on the PC. But to get the files from the .dsk image to the PC. Cp is rather tedious.

You don't say on which OS, but under Prodos, the easiest way is to look at the date modified and the file size.  You will be able to see if they are the same size, if one has been modified and which are the most recent.
