Solve : Comparing Files in One Directory to Many?

Answer» <html><body><p>I really want to get a ton of photos off my phone.<br/><br/>I have moved a bunch of them into <a href="https://interviewquestions.tuteehub.com/tag/folders-994110" style="font-weight:bold;" target="_blank" title="Click to know more about FOLDERS">FOLDERS</a> on my hard drive, but not all.<br/><br/>I know how to compare two directories, but here's what I'm curious about:<br/><br/>If I have one folder, with, say, 1,000 pictures in it (or any file, really) - let's call it "Master". And then I have a dozen folders ("Sub 1", "Sub 2"... "Sub N"), each with 300 pictures in them. How can I sift through and highlight all of the files in Master that are duped in all of the Subs, without having to go folder by folder?<br/><br/>Argh. I can't even figure how to make my question make sense.<br/><br/>You can try software such as dupeGuru.<br/><br/><a href="https://dupeguru.voltaicideas.net/">https://dupeguru.voltaicideas.net/</a><br/><br/>Thanks. It's been running for a while. This looks like it will do what I ask! Will report back once it's done.I set it up with a subdirectory on my c: drive where I copied all my phone pics, and compared it to the external <a href="https://interviewquestions.tuteehub.com/tag/directory-11615" style="font-weight:bold;" target="_blank" title="Click to know more about DIRECTORY">DIRECTORY</a> where I had <a href="https://interviewquestions.tuteehub.com/tag/everything-25538" style="font-weight:bold;" target="_blank" title="Click to know more about EVERYTHING">EVERYTHING</a> backed up.<br/><br/>It returned a list - a brilliant list - of every <a href="https://interviewquestions.tuteehub.com/tag/duplicate-433503" style="font-weight:bold;" target="_blank" title="Click to know more about DUPLICATE">DUPLICATE</a> within that external directory (and didn't highlight anything on the c:, and I'm sure there's dupes in tehre).<br/><br/>I need to figure out how to configure it to list everything in that C: subdir that is NOT copied somewhere else.... I am sure it will do it, just gotta <a href="https://interviewquestions.tuteehub.com/tag/play-251439" style="font-weight:bold;" target="_blank" title="Click to know more about PLAY">PLAY</a> some more.<br/><br/>Took about five hours to scan and build the list.</p></body></html>
