MD5 Hash of compared files???

Postby opaque1 » Sat Dec 05, 2009 5:37 am

Does WinMerge currently do a MD5 hash to determine if the files compare? Is that something that has been considered to be added?

No we don't do any hashing. Depending on selected compare method we use file timestamp/size, byte differences or textual diffs.

Using hash sums has been considered but nobody has yet implemented it. Using hashes would have some interesting possibilities. Eg. detecting duplicate files / renamed files etc. Probably caching hashes also would improve speed in some operations.
