AllDup Portable allows you to scan drives for duplicates and then quickly remove them. The algorithm used is powerful and uses different criteria to find the duplicates, like file content, file extension, file name, file attributes, and file dates. The scan settings are flexible so you can search by size conditions or masks. The unnecessary duplicates can be moved to your Recycle Bin, a backup folder, or they can be permanently deleted.
