DoubleKiller

Top Pro

Tolerates multiple sessions

I often run multiple sessions of DoubleKiller Pro, to find duplicate files among different sets of disks. See More

Top Con

No byte by byte comparison

While CRC checksums will be enough for most people, an option to check for duplicate files byte by byte would be nice. [Edit] DoubleKiller does offer that option. See More

ToughAmphiaraus's Experience

I have been using DoubleKiller Pro for eight years. I have used it in a variety of situations, on an almost daily basis. It has been extraordinarily consistent and capable. See More

Top Pro

Flexible rules for finding duplicate files

The program can find duplicate files based on any combination of size, name, CRC, and byte-for-byte. It's possible to limit search to files matching a specific name or extension pattern (great for limiting search to certain file types) as well as using the same technique to exclude certain results. You can also tell the software to ignore any of combination of read only, hidden or system files as well as files of below or above certain size and archives. See More

Answer 5

Glary Utilities

Top Con

Limited options for finding duplicates

The app finds files based on just 3 criteria - name, time and size. There's not even an option for checksums. See More

Top Con

Can be overkill if the purpose is to only find duplicates

Glary Utilities is a suite of single purpose tools and to access one, you have to download all and potentially clutter up your PC. See More

Reasonable rules for finding both duplicate files and folders
