This is how you see it. I have not heard that there is any tool to help here. I would not call this fragmentation. It is more like spreading the files from one directory all over the disk. > Splitting up partitions would reduce this fragmentation (as you are > essentially defining some "super large blocks"), and may increase > filesystem stability in case of crashes etc. > It might not affect stability but it increases the chances to fix a problem in case of a crash. I never thought of this. Erich
