MS's filesystems may fragment *more readily* than the average Linux filesystem
due to the way they allocate blocks, but at some point it is just plain *not
possible* to avoid some fragmentation. Given that I was constantly running up
against "no more space on device" errors, it's safe to say mine had reached
John Dong wrote a tool called pyfrag for defragmenting Linux drives. It's not
a low-level defrag thing, just a script that rewrites the files to try to get
them shuffled about into having as much contiguous as possible. On a disk with
only 200MB free space, though, I doubt it's much use.
