Useful but Has Issues

I used to program to identify duplicates in 250k files. It did a great job finding them although, as you can imagine, it took a while. Perhaps the issue I am going to identify is already resolved and/or I missed it in the screenshots on their website. However, if I look at the results of the scan of all those 250k files and allow it to auto pick one out of the duplicates to be saved and then just delete, for example, jpg files, I cannot go back from the Remove screen to the original scan and decide which files I want removed next. There doesn’t appear to be a way to either do that with a Back button or with a Save of the scan-to-date. So what happens is that the now 248k of files all have to be re-scanned. Again, given the size, this is a time consuming process. On the pull-down menu there is a Save and Save As item, but I could not find a way to select it and save the Scan in its current form. I do a lot of photography and Photoshop, so in the process multiples are created and this program would be good for cleaning up the mess if that simple issue of saving a scan could be addressed. All of that said, there may be a way to do this and I just missed it on their website. I would be more than happy to be corrected and change the rating. I have another 30tb of drives to scan, so being able to remove some files and then go back and review the remaining duplicates would be a big help.

Great app!

Duplicate finder found and help me delete 92 GB yes 92GB of duplicate photographs. No wonder I couldn’t even begin this project without this app. Super easy to use. The Compare and Sync by same company helped me resolve the impossible. I wanted to sync MyBook connected to my laptop with MyCloud that is on my network. According to Western Digital the only way to sync was to connect MyBook with MyCloud physically. I asked Greenworld Soft if their program would work…..and it did. Also very intuitive and I have all my docs and pics on my own personal cloud versus the actual cloud. Highly recommended. Both of the apps that I have tried.

Only Missing 1 feature but has the best feature

So lets start with the best

It Lets you have a trial, It scans 2 folders which means you can remove duplicates before you merge them but the one feature it has that the others do not is you can prioritize 1 folder to keep files in.

This app does exactly what it claims, I use it to merge folders the smart way, by removing dupicates before you put them together.


IT does not check for empty folders so not sure it has removed the folders left behind

My biggest gripe tried the trial scanned 26,000 files it worked great found 12,000 Duplicates, it told me it could only delete one at a time unless I upgrade to pro, I paid my money happily, but the pro is a different app so I had to scan all my files again, i think this should give a warning or one should pick up from the other.
