Ratings and Reviews
I've tried dozens of dupe finders. this app allows the most comprehensive configurations of any!
I've tried dozens of dupe finders. none allow the amount of contol you have on which dupes get deleted and which ones you keep as this app. For scanning folders with a lot of files/potential duplacates, you may need to upgrade to the Pro version. It is worth it! I removed almost 1TB of audio files from iTunes over the last 10 years. There was a period of time when I tunes would add the track number automatically to the beginning of the tracks name, regardless of whether it already had the track number there or not, which caused my the majority of my music library to duplicate those songs. My 200GB iTunes Liubrary would be 325GB-350GB overnight. Then it would happen again to where at one point, I had five copies of a bunch of songs with the track number listed five times in a row at the begining of the track name. Then others four times, then three times, and so on. As you could imagine, my very large, cherished music collection was completely trashed! This app is the first dupe finder that would actually marrk songs as duplicates even though the track number prefix varied from no prefix to having the rack number applied 5 times in a row before the track name. This was the first app to group those songs together when searching for duplicates.

❤️ ❤️ ❤️ Oh wow, thank you! It's so lovely to read reviews like yours!
So well worth it!
I'll be honest, I don't remember what I paid for this-- but whatever it was, it was WORTH IT. I have been trying to manage storage on my devices, but don't want to lose any of my most important files dating back so many years. I make sure to back them up, but I can never remember if I've backed them up twice or not. This tool looks through things fast, compares them really well, is easy to use, and has lots of extra features which help you choose what to keep and what to ditch quickly and efficiently. The graphic UI is beautiful, and it's SO great that you get a preview of all the files within the app so you really can triple check if it's a duplicate. It recognizes duplicate folders, too, and the merge feature is GREAT-- I just used it to get my old iTunes library consolidated into my current iTunes library on an external hard drive, and then deduped all the duplicate tracks with the same app. It works like a charm!
Thank you, developers, for a truly great little app.

Thank you for your comment 🙌 I am so glad that Duplicate File Finder Remover is a useful tool for you 👍 ❤️
Very very helpful. You will crave more.
Bottom line - use this app. It is great. Once you use it, you may find something you wish it could do to make your elimination of duplicates easier.
So, I think there could be an easier way to do some tasks if I could sort the duplicates by file. For example, I compared my download file (which really bloated on me) to my Google Drive. The results showd me all the individual file and folder duplicates within the Google Drive itself, within the download folder and betweeen GD and Downloads. But, what I really want is to see what duplicates are just in the download folder that I have already saved to various files. Then, I can eliminate those download files and folders, allowing me to then properly save or delete the balance of downloads. We receive so many attachments or web content that goes to downloads. Plus, when using google docs, office 365 online and other shared online toos, we have to upload, download files that often travel through Downloads folder. Maybe I am missing some buried feature here - but it seemed to me that sorting the duplicates by folder might get me what I want - a global list of duplicates in the Download folder compared to the global list of drives and folders I want to compare them to.
