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!
Excellent for clearing out redundancy
I've collected TBs of stuff over the decades, expanding to ever bigger HDs. It got so overwhelming that I just figured that space was cheap. It kept bothing me though...In the back of mind, I was sure I was a digital hoarder. This software came to the rescue, clearing out almost 400 GBs. Because I had so many files on this 14TB drive, I could have never gone through all of the duplicates it found. Luckily, it seems to have an AI component that can use your discisions on which file to keep to auto select working at it's best. I only changed a few of the auto-choices, but then found that I no longer needed to do it when it got to the point where it selected everying I would select. In any case, the autoselect really does make this software even more spectacular with the ability to delete batches of auto-selected files with one click. It has other features to help you schedule a cleanup. I find that after the first one, I don't need to worry about it for awhile.

Thank you for taking the time to write a review. We really appreciate it 💙 It’s through feedback, such as yours, gives us motivation to add even more valuable features to our apps.
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.
