Tri-CLEANER includes very interesting features. It surveys your hard disks contents and records all the changes, even during your absence. Many weeks later you are able to identify when and what was modified on your disk. It uninstalls any software, including the files created at the first launch of the application, invisible files, etc. Tri-CLEANER checks all items added, modified or removed. It cleans your hard disks by moving to the trash all unused items (alias, preferences, empty folders, duplicate files, etc.).
