NoClone

NoClone allows you to safely find and remove duplicate files.

The program doesn't just work on comparing CRC checksums, as it tends to do with some competitors. This product uses real-time comparison and detects duplicate files regardless of the file name. You can set search limits in the form of specific file types (images, programs, etc.) as well as size, date or location. You can choose to delete, move or copy the data.
Results can be exported to a CSV file.
The program can display a list of files that have the same name, zero size, or files that had reading errors. Images can be displayed in preview.
