The disk becomes fragmented just by using the computer, moving files,creating new files, etc.. The data is no longer contiguous so Windows writes the data to the next free cluster of space and this causes data to become "fragmented" so when you run a defragmenting program it places the data in a contiguous order. And I've read once a month once a week. I've even seen people say they do it once a day. Unless you're constantly installing things and deleting them once every few weeks should be good. It's been ages since I've lasted done one of those because by the time my computer starts slowing down I format it and start over.

There was a post on memory awhile back where the subject of defragging came up. Thread is here.

The post in question:

I still find it interesting/amusing/annoying that Windows filesystems still seem to require explicit defragging from time to time.

Microsoft's own Gordon Letwin designed the HPFS filesystem in 1989 that I use on my OS/2 and eCS machines, and I've *never* had to defrag those partitions. Why their newer NTFS filesystem isn't similar in its basic behavior is something I've never understood.

Fragmentation, by itself, isn't harmful in most filesystems anyway unless it causes a performance hit.
I usually compare fragmentation to someone digging thru a filing cabinet. While many people put stuff back where they found it, not everyone is quite so neat.

Windows is NOT neat. Liz

i'm a big fan of raxco perfectdisk. not only does it defragment the harddrive, it places commonly used files closer to the front of the disc. i've noticed significant performance boosts over the windows defrag tool. they have 1-month trials available so that you can see if it's worth buying. if you don't have a really big harddrive or a really full harddrive, the difference may not be big enough to be worth the price, but on my tower pc i have a 320gb hd and perfectdisk has been a lifesaver [/salespitch]

This behavior is why, when you accidentally delete a file or files you should stop and do nothing else on the computer until you do a data recovery for the files. If you continue writing to the disk you run the danger of overwriting one or more of the clusters that Windows has marked as unused (the next free cluster can be one that has never been used, or it can be one you just freed up by deleting a file). Oops!

good advice. when you delete a file, it's still on the disc, but your OS just doesn't acknowledge it anymore. as soon as something else is stored, the OS will overwrite that space.
