Re: Why ext3 doesn't need defragmentation ?

[Sam <transiency@transiency.org>]

Hi Kamaraju,

I am also not an expert in filesystems, however, I do know that the new native linux fs ext3 has what is called "journaling". Linux keeps track of where everything goes, so it doesnt get disorganized. Once in a while you could run fsck if your really concerned about it.

I am not a file system expert by any means. Sometime back I read the
following link and found that it explains this issue very clearly in
layman terms.
