That is an option as a last result , but the back up is pretty important, and I have some stuff that I need to access just incase , I just want to delete a certain file, thank you.
I thought you had backed up the TC..
Permissions are tricky things.. because it depends under what Mac and user you created the folders in the first place.
The best way to handle things is via terminal and get super user access.
Just be very very careful because from root you can delete everything.
