Well, normally a folder on the desktop should be unlocked. It says something is wrong with your permissions, or some background application is running that has assumed ownership of the files. To force all such applications not to be running restart the Mac holding the SHIFT key. Also try repairing permissions with Applications -> Utilities -> Disk Utility -> select hard drive in Disk Utility's window and select First Aid.
If after repairing permissions you can't at minimum send the file to the trashcan, and rebooting with the SHIFT key held down doesn't help allowing you to move the file to the trash, then:
1.
Backup your data*
- 2. Remove any network connection.
3. Dismount and physically disconnect any data devices that are not boot devices (drag their icon to the trash).
4. Open Applications -> Utilities -> Terminal
5. Type at the terminal window WITHOUT hitting any return key:
sudo rm
5. Drag an offending file into the terminal window. You can do with this folders too, but additional commands and risk needs to be assumed. Make sure there is a SINGLE space between the file path and the word "rm" by using the left/right arrow keys to navigate the cursor. Put the curser immediately after the path of the file with no spaces after the end of the path. Hit return.
This will force delete the file once you enter your administrator password.
Do this for each offending file.
