I bought an HP desktop a couple years ago that's still running strong. In the last year or so, I've noticed it slowing down a little bit, so I've been trying to figure out why. About 6 months ago, I was loading a program and got a message saying my HD was full. What? I filled up a 1 TB HD? Sure enough, it's about 93% full.
So, I went into clean up mode. Deleted some unused programs, moved several catalogs of RAW files over to external HD with their jpegs. Thought that would be enough. It dropped me to about 90% full.
So, I need some guidance. When I look at uninstalling programs, how do I analyze what I can and can't delete? Last thing I want to delete is a program the computer needs to run. Some of them I know what they are, some I don't.
Any tips on cleaning this up?
BTW, 2 years of RAW files (about 15K images) took almost no room on my external HD, so it's not the files I have on my computer.
