Try to keep that clear.
1GB of free disk space won't help in today's PCs. I've found that sometimes I can boot to safe mode to do more cleanup. Since you didn't share much about the PC, let's hear more.
There are some viruses that fill disk space but you didn't ask about virus issues.
I keep getting low disk space warnings. I cannot open programs, and cannot use certain programs, etc. When I delete something, that amount of storage is not added to the computer. I can delete 1G of memory and it will still show 0bytes of storage.
I do not know what to do. It's like when I delete something, that space is immediately taken up.
PLEASE HELP, THANK YOU
