Free app to do "diff" on two folders?

  Dare Devil Denis 13:49 31 Dec 05

I'm looking for a simple free app to do a recursive "diff" on two folders. This is so that I can compare the "My Pictures" folder with the version on my external backup drive (to make sure no pics have been accidentally deleted).

The closest I've found is "CSDiff" which does the job but also does a binary comparision of every file (in this case jpegs) in the folder and subfolders and so is veeeery sloooow. I just want something that checks that there are the same files without checking that each file is bitwise identical.

When I want to compare the contents of two folders on different drives I open up both folders onto my Desktop and place them side by side and then I am able to compare them both. I never use software to do this as it is not needed.

Yes, but I want to check recursively within folders. I have about 100 folders at the top level. Each of these could have many subfolders, with hundreds of pictures in each folder.

Download PowerDesk from the PCA download page. It has a "Compare" module.

used to be on page 2 but now appears to be on page 7. Scroll down to Powerdesk V5.

I once used for the same purpose.

Thanks guys. I just realised that I already have exactly what I'm looking for already installed on my work PC. DOH! It's "Beyond Compare". Very good app. It has options to ignore the file contents (as I wanted), or compare by file size, size and CRC, or a full binary comparison.
