We found Nektony Disk Space Analyzer to be a great tool for users who are looking to free up valuable disk space on their computer. The software’s user-friendly interface and fast scanning speed make it easy to identify the largest files and folders on your computer.
Within 15 minutes, I deleted some old movies and large size game apps, and I saved 34GBs of space. As Wayne from Wayne’s World would say “Excellent”!
Very useful because in addition to a graphical display of directory size, there’s also a list of the largest files in those directories. The most useful of this type of program that I’ve found. So far. Very fast scans, too. Nice job.
Just recently had to solve a loss of aprox 150Gb of disk space on my MacBook Pro. With my limited skill level and support from the techs managed to retrieve the full 150Gb back. The Disk analyser program was super simply to use and the tech support staff go out of their way to help. These guys are awesome!!
I have been using the Disk Analyser app for a while. It has worked great for me, especially to delete all the stuff iCloud was downloading over and over when I had internet interruptions due to my VPN. Even the Apple adviser I called about the iCloud issue liked the app!
It stands out for its intuitive sunburst-like diagram visualization, helping users easily identify and manage large files and folders. The app is user-friendly, supporting various types of volumes and offering real-time scanning.
