Re: Various Questions (2)
On the issue of defrag,
Unlike Windows, any new file written in a UNIX style system is written
contiguously. If a file is copied or moved, like when it is renamed,
if it was fragmented before it will now be contiguous. Over time,
UNIX file systems self-defrag.
Also in a UNIX style system, having the disk heads moving "all over
the place to find file fragments" isn't a bad thing, because the
system is doing other things as well, so having the heads moving
around means that the OS can read/write other things too, without
causing IO bottlenecks.
So don't bother to defrag. It's only on a Windows where new files are
written into the first available open space no matter how small, that
file fragmentation is inherent in the system.
