Virtual memory, system cache file, application software cache file, registry file will occupy the system disk (general c drive) space, you may have uninstalled The software, and then stored in the cache file in the C drive, the registry information will be deleted, or after you restart the computer, the system redistributes the internal files, resulting in a reduction in the storage space of the C drive. In short, the operation you mentioned does not delete the system files. It is not so easy to delete the system files. Don't think too much, as long as you don't move the files in the c drive, there will be no problem





There may be software installed in





The system is normal, there may be software installed on other disks, but the software Stored in the c drive, so you will clear the other disk will appear C drive less, you look at it,

Then look at the system is not normal, use the software to test it, nothing It's OK






There may be hidden files.
