++ checksum will now post the path that was hashed/verified in the final tooltip, in case you forgot what it was you were hashing, e.g.. checksum completed verifying: e:\music\jazz\ in 3.55 seconds.. [100% OK] ++ Added new method (actually, the original method!) for testing writeability of directories. Normally we use the most accurate method, which is to write an actual test file to the directory. However, this will also change the "last modified" timestamp on that directory. If you would prefer this to /not/ happen, you can do (in checksum.ini).. relaxed_write_test=true which will instead rely on the system's "read-only" flag for the directory. This works in most ordinary scenarios. ++ Added Individual file verification search feature. This enables you to verify a single file, anywhere in your system, /from/ anywhere in your system, regardless of where its associated .hash file is in the file tree. This is extremely useful when you want to verify a single file but don't have an individual .hash for it, especially when the entry is inside a .hash file with thousands or millions of other entries, or you aren't sure exactly which .hash file contains the entry. Normally, for verification you feed checksum .hash (or .md5, whatever) files and it scans them looking for matching files to hash. Using /this/ method, you feed checksum a regular file path and it scans your .hash files looking for a matching hash entry! checksum will search up the tree, first looking for matching individual .hash files, and then folder hashes, all the way up to the root of the volume until it finds one containing a hash for your file, at which point it will verify that one hash and return the result. The final dialog will also tell you *which* .hash file contained the entry for your chosen file. Thanks to Brett Lang for the original idea, which he presented to me as a DOS batch script doing a similar thing. I have to admit, it took me a while to get my head around the idea (it's just so back-to-front!), but once I did, I immediately saw how useful such a feature might be. You can enable this operation by using an "i" on the command-line, think "individual" file verification, or perhaps "Inverted operation"! e.g.. checksum.exe vi "C:\some\path\to\file.ext" This works best as an Explorer context command. Future versions may have this built-in to the installer setup. For now, an example .reg file is at https://corz.org/windows/software/checksum/files/
