Right. I've defragmented my hard drive several times in the past and frequently been left with a message that some files couldn't be defragmented. If I cut these files, then paste them in a different location, will they become contiguous? Or doesn't the moving process really move the file, just the address? If I move the file to removable media before moving it back, will this help? I accept that in the overall scheme of things, a fragmented file isn't going to make an awful lot of difference (or perhaps I'm wrong?), but I'd like to tidy things up. Also (I've asked this question in part previously), if I move my Program Files folder to the D: drive partition (which is substantially empty), will new files relating to it be created in the current C: drive folder, or will a new folder be created automatically in the D: drive? If I've not made myself sufficiently clear, this relates to programs that create separate data folders in addition to the folder that actually runs the program. This also relates to tidying up the hard drive - I intend to archive old data onto DVD-RW, but I'd like to shift the program itself onto the D: partition which appears to be underused. This would create a larger space on the C: drive, reducing archiving frequency. While I'm on, will increasing RAM really make a difference? While I accept that a larger RAM will speed up CD/DVD-based games (which I don't play often), would it make a major difference to web-based games which are dependent on wireless and broadband speeds? And to the downtime that results from antivirus and anti-spam checks?
