What is TreeSize Pro?
TreeSize Pro It's a disk space manager for Windows that allows you to allocate, manage the size and free space of folders and drives. The principle is that it scans for large files, including old and duplicate files, and then displays them in a 3D map, sorted by the amount of space used. It also shows the number of files, last access date, file owner and permissions, NTFS compression ratio, and much more.
Once we know which folders are taking up more space than usual, we can access them and decide which files or folders to delete. Sometimes these files are ones we no longer use or are from old programs that we've uninstalled, but they haven't been deleted even when using an uninstallation helper program. Revo Uninstaller Or IObit Uninstaller Anyway.
In practical use, it has been found to be very useful, significantly reducing the space needed for a Windows system that has been in use for many years. If anyone wants to reduce system space but needs to use a good automatic junk file removal program, CCleaner Or Wise Care 365 And since it doesn't delete as many junk files as expected, this program is a very interesting alternative.
