FreeFileSync Forum

Hi Sven,

as far as I can see this feature request is all about performance optimization. But think about it:
Deleting some files and copying them again is a lot faster than reading all(!) files' content in order to get their checksums.

Well yes, I think you may be right regarding ...

FreeFileSync checks if two files are equal by comparing their content directly. This is the most efficient way to compare files.
When you want to find files that are equal from a group of files, you would need to make checksums for each file. That's no problem so far.

But I don't really see this ...
