  • How to Find Unique Files


    Finding duplicate files is important. However, finding "un-duplicate" or unique files is also important to me. I just don't know how to easily find unique files.

    Here's a scenario: You want to format an old drive but want to make sure there's no files on the old drive that you wish to keep. In my case I assume I have all the "keeper" files somewhere on my working drive(s) but I'm always wondering if I missed that one important file when moving data around. As a result, I have a bunch of old drives that I'm afraid to format "just in case" I missed transferring an important photo or file.

    To add one more layer of difficulty when comparing files; I'm always changing my directory tree structure on my working drive. Therefore, I most likely have all the files from the old drive on my new drive but not in the same directory structure. As an example: A photo of an old girlfriend needs to be relocated from the "girlfriends" folder to the "wife" folder after marriage ;-) Then I password protect the girlfriend folder.... (sorry, delete the last sentence.)

    In conclusion, is there an operation to scan two drives or two folders and then list only the unique files? This way I could just look at the unique files on the drive I intend to format. If any of the unique files are important to me I would move them to my working drive.

    I apologize in advance if his is a common feature of BC; I'm just learning the program.

    Thanks to all...

    With a constantly changing folder structure, you can try using our Ignore Folder Structure option. This assumes all files have unique names in all subfolders, however. If multiple files have the same name, it may not align the pair you expect. Any Orphans in this view would be files that do not exist on the other side (due to a name difference).

    If files have been renamed, BC3 does not currently support scanning the contents first. Do you think this might come up as well? If you back these renamed files up to a central location, and then run a duplicate file finding software on that location, you could then find the duplicates.
