While trying to enable my Microsoft Office 2008 to allow me to enter a new code I pasted a rm command into the terminal, as directed by someone in a forum. I think it may have wiped out my desktop because now the entire desktop is gone. Will Diskwarrior help me with this or is it a lost cause? All my music and photo files are fine, it is just everything that was on the desktop, which was a lot. Please help.
