Duplicates
The Duplicate files option in the Disk Cleaner scans the selected drive partition or a selected path and searches the copies of same file stored in different folders.
This is useful in removing redundant or duplicate files stored in an obscure folder and you could have forgotten storing those. The files are identified as exact copies by performing a checksum between the current reference file and all the files from the search path so that the duplicate files can be detected even if they are named differently. Maintaining several copies of the same file not only occupies the disk space unnecessarily but also confuses the user due the bulk it adds.
