FindDuplicates accepts one or more paths to check for duplicate files.
Files are considered duplicate when their contents are identical. Unlike other duplicate files finders, FindDuplicates does not care about file timestamps or any other unreliable information. Files are compared byte by byte (of course a bit more sophisticated). Again, that means files are treated as being duplicate files when their contents are identical, no more, no less.
The software starts by comparing the largest files first, and then checks the smaller file sizes. If two files don't have the same file size they can't be identical. Each file is read in blocks to avoid more read operations than necessary.
Since FindDuplicates doesn't show a progress bar to save time the "best guess" for the remainder of the process is to display the files' sizes it currently compares.
When more then one path is provided the software checks for duplicates between all of them. For example, if there's a folder 'folder1' and another folder 'folder2' with an identical file in each folder, it is found.
Assuming the two files are identical,
FindDuplicates would then report:
(1) 21883418 octets, folder1\file1.dat
(2) 21883418 octets, folder2\file2.dat
