If they're part of some applications, I'd leave them alone. It's so easy and inexpensive to add hard drive space these days, I have to question why you're considering this. A couple of months ago I bought a 2 TB drive for $75. That's a whale of a lot of space.
i have found over 700 jpg's some are pics of lumber,bears,roses,etc. i am wonder if i can delete these with out trouble? as i never have used them in any of my pc's. i am using a acer laptop aspire E-15.please help me asap. thank you for your help.
