After using Linux for a while, I noticed that there's very little for defragmenting.



The only defragmenting program I found was e4defrag, a CLI executable that defragments ext4 filesystems.



However, besides finding e4defrag with apropos, I have found very little documentation (and programs!) about defragmenting in Linux. Having a Windows background, I found this surprising, as (in Windows) it is common to manually defragment your hard drive or have Optimize automatically do it.



Do Linux systems (on an HDD) need to be defragmented? If so, is it done automatically?

  • an EXT[234] partition that's under 90% full tends to have a very low fragmentation level.
