Those who have come across files don't delete, here are some
suggestions to try.
1. Make sure that the file attribute is not READ-ONLY.
To unset read-only, do this:
Then try deleting the file again.
2. Delete the file in Safe Mode. Make sure that the file is not
READ-ONLY. Refer to step 1a to 1d to figure out how.
3. Change the file extension.
Try deleting the file again. You can do this in Safe Mode as
well. Make sure the file is not READ-ONLY.
4. Use
FileASSASSIN.
5. Still can't get to delete it, set the permissions right.
Try deleting the file.
6. Still cannot, create another account with administrator rights,
drag the file to the new account and try deleting it. Remember to
log off, not switch user. If you use switch user, you might get a
"file is in use" error.
7. End Explorer and take note of where the folder where the file is
located.
8. Use Unlocker.
9. Still, if it fails, reformat and reinstall Windows. This is
guarantee to work, except that instead of deleting one stubborn
file, you delete all the files and reset your PC back to factory
state. Remember, backup all your stuffs before trying this last
method.
Note: This is only for files which give errors like "file in use"
error. If you can delete a file, but it keeps coming back, then you
have malware, not stubborn files.
