If you are trying to delete a file or a folder in windows 10 and you get a message that says item not found, you can still delete it but in a different method. To delete it follow this simple tutorial.
1. Find the folder you want to delete on it’s directory, hold shift button on keyboard plus right click on a blank space, from the dialog menu select “Open Command window here”.
2. The command prompt will open. Here type dir /x to list all folders in that directory and look for the one you are trying to delete, you only need the <DIR> of it (in this case is TESTFO~1)
3. Now type in rmdir /q /s and the folder <DIR> (TESTFO~1) hit enter. This will definitely delete the folder.
This really helped me. Thank you so much!!!
