    Compare 2 folders, copy uncommon to a new folder


    Hello folks,

    I have a task of sorting 3120 pdf files into various folders depending on their topic. These are all research papers I have downloaded over the period of last 12 years. Was using a bilbiographic application to keep them in check, but after a decade, it failed. Now I have 3120 pdfs in One folder. These files relate to 6 different projects I work/worked on. I need to sort them to the respective folders so that I don't fiddle around the old files, those I need but don't use on day to day basis.

    Sorting them on date is not a solution.

    I use 'Everything' to search files on the drive. I used some keywords to 'filter' the files and sorted about 50%. Now I need to sort rest of the 50%. I will have to go through them one by one.

    So the question is, is there any way that I can run a folder comparison utility and it spits out the UNCOMMON files in a new folder. Deduplicating applications delete the common files, and I want to separate uncommon files.

    Anybody has a pointer? It may be very easy with the right utility, but as you see, I am not well versed with this.

    Many thanks in advance.

    You could run a batch script; no software required.

    What is your definition of a "common file"? Same filename? 1:1 binary duplicate?

I need to compare 2 very large folders. One is a backup of the other, so I expect them to be identical, but I want to verify that each file is truly identical (byte for byte). The folders have many subfolders and thousands of files, some over 1GB is size. So the solution must operate as fast...
Hello, I just set up a new laptop and screwed up the name, but by the time I accepted it would be a problem I'd already moved everything from old laptop/re-installed programs/etc. So, I used the "Copy To" solution to move the wrongly named profile (WP) over a rightly named one (RP). All seems well...
Hello folks, I wonder how can someone compare two folders and delete unique files from one folder out of the two. In ideal case, I am looking for an utility that will look similar to CloneSpy (http://www.clonespy.com/images/screen.png) but instead of deleting duplicate, will delete Unique...
