How to find files that either shouldn't be there or are eating up memory
Hi,
I download a lot. (I have 12 TB external and I've used it all -- several times.) I'm afraid that at some point I must have downloaded something I shouldn't have, as my computer has gotten slower and slower over the year. Is there a way to find out what has been added to my OS/computer that wasn't in the orignial instal?
Also, is there an easy to follow tutorial that explains the the data generated in the Activity Monitor? (The CPU might show 94% idle, the System Memory 12 of 16 GB free, and Disk Activity, Disk Usage, and Network all at the very low end of the usage bar, but it still takes a bit of time to process my requests.) I'd like to better learn how to trouble shoot on my own.
Thank you much,
