I'm using version 4.0.4 RC and have folders full of passwowrd-protected zip files created by my backup program. There are thousands of exact duplicates with just one a character difference in the filename. The duplicates are of the same size. They can be opened with Winrar, which shows that the contents are identical (same size, date/time and CRC32). But the MD5 hashes for the files (checked via FCIV) are different. So when I use the Contents scan type, Dupeguru says "No duplicates found". Can DupeGuru be set to use the info stored within the ZIP archive (size, name and CRC32 ) to determine whether zipped files are duplicates or not? If not, that would be a nice feature to add.

Thanks for creating such a great program!
