Below is how to permanently delete files from hard drive you can try.
Sometimes, Windows can not delete a file or move file because it is in use by a program. Here are some ways to move files to Recycle Bin (or somewhere else).
Look at the error message.
Sometimes, Windows can give you the information right away. If the dialog box tells you to open the file in Word, you have idea what to do next. But if Windows doesn’t give the information, you have to find another solution.
How to permanently delete files from hard drive with Unlocker
Use third party software.
There are several utilities that may find out what program is currently holding onto your file and set the file free for deletion. You can use Empty Loop’s free Unlocker. This software has integration with file explorer and has many options for how to handle the file.
Once installed, you can click the stubborn file and select Unlocker to free it up. The process path columns will tell you which program holding the file, so you can close it. If that doesn’t work, you can click Unlock with choosing pull-down menu to erase. If that doesn’t work too, try kill process.
Restart into Safe mode.
If Unlocker fails, or if the PUPs worry you, rebooting into Safe-Mode will likely do just fine.
