  1. Add Directory Report to your list
    It can find duplicate files based on the same name, size, CRC and comparing byte by byte.
    Finds duplicate directories too!

  2. Cynthia, You should use DuplicateFilesDelete, for deleting or removing duplicate files and images form your windows. I personally uses this and I’m quite satisfied with this. You must try this.

  3. Sometimes we get an error when we try to delete a File or a folder for no reason , but of course there is a reason.We have many damage file or blocked files.Do not worry if we want to remove the error files or too long path files from our system,here I suggest a smooth way.So use “Long path tool” software and keep yourself.

  4. Enough with DuplicateFilesDeleter already.
    It’s a piece of junk.. Gives lots of errors and crashes frequently.
