Question / Problem
How do i know what files i need to keep and what i can delete?
Answer / Solution
Since we do not know which files you have on your disk, and also do not know which files you or your colleagues or family members might be interested to keep, we cannot give you advice here. The results of the TreeSize Temporary File Search and the Browser Cache Files are quite safe to delete. If you delete files, only delete them to the recycle bin or move them to a different path, from where you can recover them again a few days after you deleted them, just in case you deleted a file you still need.
