I tried that but the program doesn't open

>>118312
did you try terminating the process that is using the file?

>>118312
Restart your pc, if that doesn't help, boot from a USB with a live image of Linux or something

what program doesn't open? You right click on the thing you want to delete then scroll down to unlocker

>>118312
No.

If it were, literally all the locking guarantees Windows offers wouldn't be worth shit.

Unix fanboys will tell you advisory locking is better than mandatory locking because you can delete files whenever you want; the truth is that mandatory locking is really hard to do properly; windows does it properly and unix doesn't and there's a fox/grapes thing going on; and mandatory locking is better than advisory locking because when you lock a file, the operating system (which, to processes, is a force of nature) prevents anything from deleting it from under you.

Suck it up and terminate the process. The OS guarantees that you can't delete or modify it until the process gives the lock up or terminates.

You need to run it from the command-line, as an administrator.
