Defragment software for Linux
 

Hi, i need some software to defrag my partition. In Windows, many choices for me, but in Linux, why have little ?

Can you tell me some good apps for defragment ? And if it can defrag both Linux and Windows partitions, i'll be very happy/

No you don't.

Some reading about the reasons why:
Why Linux doesn't need defragmenting
Linux file system defrag

Cheers! ;)
