Disk Cleanup Pro is a Mac utility for optimizing the performance of your system and reclaiming space on your computer. The program provides you with a quick and simple way to get rid of all necessary data from your Mac, such as cache files, duplicates, unused applications, and many others.
As soon as you launch the app, it immediately starts scanning your system. Once the scanning process is complete, it provides you with a complete report and lets you know how much disk space you can save by deleting the found unneeded files.
Furthermore, the program comes with a built-in app uninstaller which might prove to be of good use for completely removing the tools you no longer use. You also have access to an integrated duplicate finder and an efficient tool for locating and deleting large files from your Mac.
The only problem I have with this program is that it lacks the ability to preview the found duplicated files. Hence, you cannot compare the found duplicates directly from the app's interface. Instead, you need to locate them in Finder and open the files for comparison.
Still, this program comes without a price and provides you with many useful advantages. I'd say it's worth a shot.
