Disc full message, what to do?
I have a iMac about 2 years old, I keep getting the message that the scource disk is full and that I need to delete some files
1) What does this mean?
2) How do you delete files?
3) What files can you delete?
4) Can you fit a new / bigger drive?
5) How difficult / easy is this to do?
Thanks in anticipation
Is this a good question?
