I'm looking for a utility that will compare the files in two directories (and subdirectories) and report any that are different. I'm backing up images onto DVD and occasionally I get a verfification error. Unfortunately it just says "Verification failed - one or more files were different". It doesn't tell me how many files, or which files (dumb software - RecordNow). I'd like to compare the source directory to the DVD copy and figure out if it's one unimportant image or 100 important images, so I know whether or not to burn another copy or just add the one bad file to the disk (or another disk). I know I suppose I should burn a new disk to be safe, in case the disk itself was bad and so prone to failure, but I'm still interested in which files failed to verify. I did a web search but didn't come up with any simple utility that will compare directories and report differences in any files. All I can find are utilities that find files that are the same (duplicates) in two directory stuctures. Anybody know of one (freeware prefered, but anything is of interest). I'm running Windows XP Home. I tried ExamDiffPro, but it only compares individual files or directory structures, it won't compare all files in all subdirectories as far as I can tell.
