Today I was erasing some music files from my external hard drive as well as some photos. I was erasing and going to update and back up again. However, it will not let me erase them from my computer because "I do not have sufficient privileges". I have tried using the option button to force erase and that does not work. I am not familiar with typing commands but am willing to try. These files only appear in my trash when connected to the external hard drive but they are large files. Any suggestions how to get rid of these? Thanks ahead of time!
