This sounds serious. I backed up all my data. I don’t plan on deleting the file. I will leave it on my desktop to remind me to try to find more on this problem. What would you do with the file?

I was cleaning up an external storage media and a folder called: %SystemDrive% appeared on my desktop. When I click on it, it contains a folder called:
ProgramData, with these folders as follows:
-Microsoft
--Windows
---Cashes
When I click on Cashes I get a list of data base files. Can I put this folder back where it belongs? It is a hidden folder inside windows(C)....
