Failed to delete a folder in my PC

Dear All

This is first time to post in this forum.
I have a folder in my PC which has unnecessary data. I want to delete it but failed. a massage appears that this folder is open in another account but actually it does not open in anywhere. I have scanned it for virus but no threat found. What to do?

 

Unlocker
Emco Move On Boot
UnlockIt
FreeFile

 

what exactly are you trying to delete?
anyways, Unlocker can remove the file. Just don't do anything that you shouldn't do, like accidentally get rid of Windows
I don't think it can delete whole folders, but it can delete the things INSIDE
