If you’re running duplicate finder across an entire filesystem, it will take a long time. This generally should not be done, as you can do a lot of damage if you don’t know what you’re doing. A healthy Windows install will have many duplicate files.
Sometimes files cannot be cleaned because they are being accessed by another process. If you notice the same files recurring quite frequently, it may be best to exclude them from future scans.
