Windows native compression is what I use. From XP to 7 it's native and has turned out to be safe and free too.
The title says it, although I want to be able to do high compression on regular files/folders like .txt, .docs, .pdf, and regular folders you'd see on the Windows desktop that a person keeps things in like a folder full of images, for example. In other words, I do not want to make archives like zips, tars, etc. just the other stuff I mentioned.
Are there any programs that can do this? How about 7zip?
The reason I want this is I'd like to be able to compress as much as I can on Windows, compression better than Windows default can deliver, so I can not use as much space as I do now. I have a lot of folders with lots of pics in them etc and pdf's which are quick huge and a few .txt files like this too. This is the stuff I want to be able to compress, if possible.
