She is now on a NTFS system. How important is defraging under NTFS.
Not very, unless the file structure is operating close to capacity and
files are constantly being created, deleted, and grown or shrunk.
Servers often meet these criteria, but desktops usually don't.
My knowledge of the structure of the disk under NTFS is almost ZERO.
It's vastly superior to FAT and pretty much damage-proof, but it can
get fragmented if you are using almost all the capacity of your disks
and you modify the structure a lot.
I defrag once in a great while, but since I'm not anywhere close to
capacity on the drives, there usually isn't much fragmentation.
Does defraging make it easier to recover files?
Not really. But NTFS is extremely resistant to file-system
corruption, so losing files that way is unheard of. I've never seen
an NTFS partition become corrupted.
NTFS is also designed such that deleted files cannot be recovered (for
security reasons). The data isn't actually erased (unless you set a
special option that isn't exposed via the user interfaces), but the
design of the file structure is such that it's extraordinarily
difficult to determine where a given file might have been once the
file is deleted. Thus, on NTFS, don't delete a file unless you really
want it gone forever, because you can't just flip a bit to get it
back.
