I know that "C" drive can become heavily fragmented with normal every day usage due the the operating system being on that drive (temp files, swap file, etc). I have FSX on another drive and defragment it once a month which I know may be a little excessive if one isn't adding or removing addons. I also defragment "C", but not as often because of the time factor. It takes most of the day.My question is;On a freshly defragmented drive, "C" drive in this case, if a series of files (say 2 or 3 gigibits worth) are not modified in anyway either manually or by the program that accesses them will they become fragmented over time as the rest of the drive becomes so? I would assume not, but I'm not certain.

Yes it would - http://en.wikipedia.org/wiki/Fragmentation_(computing).Best regards,Jim

I suppose it depends on how many sequential reads from disk are being done. For example, it could be that the paging file is fragmented, but since reads/writes I think would be 4kb only at a time, I'm not sure it would make a diference. Also extra RAM in the system is used for the system file cache, so the file might already be in RAM.scott s..
