    Do I need to defrag HDD in Linux? (ext3)

    I recently moved around, deleted and just had a general day of cleaning up the file structure on my pc. HDD contains about 2 TB of data. Around 1 TB was relocated on the disc, and yet another TB was moved to external drive.

    In windows this would likely means it was time for a defrag. Can't find any defrag tools in Xubuntu and that lead me to remember I read somewhere that there is no need to defrag when running Linux.

    So is that correct? Is defrag only for the wondows world and something we never need to do in Linux?

    If not is there a way to do a defrag from terminal?

    I'm not familiar with any defragging tools for Linux, but it's possible there is some obscure tool out there that I've not heard of. Having said that, I've been running Linux for about 11 years now and have never defragged a Linux filesystem.

    Linux file systems seem to have built-in intelligence that prevents really bad fragmentation. I've never heard of anyone needing a defrag tool.

    Translation for win-dmg-usr's:
    If you find any so called "Defrag"-software for Linux ...
    It's probably male-ware ... targeted on ex-windows user

    Linux file-systems like xfs, ext, ... don't need it.

    I found this discussion on e-How.
    How to Defrag in Linux | eHow.com
    Evidently it can be done, but isn't usually necessary.

    Nah. I dont worry anout anymore. Consensus seems to be no needs for defrag on linux. So I leave it as is.
    Anyway I use ext 3 not ext 2 so that would'nt work for me anyway.
