Hello,
it appears that ext3 doesn't need a real defragmentation operation

I mean a specific tool that need to be run sometimes related to

Is it correct ?
Right.
If so how it works ?
It shoots for blocks most able to handle the entire data chunk instead
of shooting for the first available chunk no matter what like every
Microsoft filesystem does.
Keep in mind, though, that this will only prevent fragmentation if
there's a sufficient amount of free space on the disk. If you
constantly keep the disk close to full you will still get
fragmentation, just because there aren't many free space chunks to
shoot for.
