hi,

I'm trying to compare a folder against itself for duplicates using the matching file contents mode. The folder is big; 132 gig, and has 26,415 files. Have I run into a practical limitation on what Dup. Cleaner Pro can handle? Please see attached screen shot.

I'm running Win 7 Pro 64-bit on a fast desktop with 8 gigs of RAM. The system is managing virtual memory and I have a 240 gig SSD.

You're using 8 GB or RAM.
Is Duplicate Cleaner using the majority of that?

Anything special, odd with the ZIP files, like are there huge directory trees zip'd up within?
Is there sufficient disk space to extract the zip'd files, sufficient space on your %TMP% drive too (if different from C:).
(I'd suspect their contents does need to be extracted.)

Hmmm - has it got very large (duplicate) files sizes? This could cause excessive memory use. The actually amount of files being scanned is fairly low.
