nektony1 added Cisdem Duplicate Finder as alternative to Duplicate File Finder- tadeomcdaniel833 reviewed Cisdem Duplicate Finder
I had an old 1TB external hard drive I’d been using for years to store my work files. It was almost full, and I knew a lot of that space was wasted on duplicate files. Cisdem Duplicate Finder scanned the entire drive in several minutes and found hundreds of duplicate documents, videos. I was able to easily preview them and delete the unnecessary copies. It helped me free up more than 50GB of space.

Have used this duplicate finder since last year and it works fine. The device cleaning has to be a regular routine so my computer and phone can be light without almost same photos and videos. That's what this cisdem product can do for me to find and remove those repeated files. Simple but useful. Thanks.

I appreciate the speed and efficiency of this program, however, layout looks oversized... and I've got old eyes. Tried it on another pc to make sure it wasn't just a setting. Uncomfortable for me to want to use. Google search made it seem like this is just for Mac.
I use it for images and if you make it use the slow algorithm it works great but its extremely slow. The free version is ok but has ads from time to time popup of the premium version. From the free options it has the best UI whilst still being the most functional (Look at comparisons to other apps to see what I mean).
This is an app that has a lot of potential and it works great on local harddrive and SD card, or USB drive, also it can scan the itunes library, a feature I really like.
