12.04 LTS and I mistakenly protected a file named set using:
chmod 700 /home/jatin/Desktop/set
How do I unprotect it?
Step #1 = In terminal type "gksu nautilus".
Step #2 = Navigate to where the file or folder is.
Step #3 = Right click the file or folder, choose "properties", choose "permissions", and then choose the desired access settings. You can also change who owns the file or folder if you don't want it to be owned by root.
Don't forget to close the nautilus window afterwards - it runs with root permissions.
