Just remember that it is a good idea to have a least 10% of the filesystem you want defragmented available for the entire process to be successful. And don't forget, UNMOUNT THE AFFECTED FILESYSTEM BEFORE YOU RUN DEFRAGMENT!
That link links to download.tuxfamily.org/optimization/OptimizationKit/v0.1/tmp/ for ok_defrag, which returns 404.
Does anyone has a new link?
I think I desperately need to defrag my file system:
$ ls -Alh hg/programs/internet/VideLibri/videlibri

I'm not sure exactly which filesystem you are using. But if it is ext4, then you might use e4defrag, which is part of the e2fsprogs package.
e4defrag - online defragmenter for ext4 filesystem
e4defrag reduces fragmentation of extent based file. The file targeted by e4defrag is created on ext4 filesystem made with "-O extent" option (see mke2fs(8)). The targeted file gets more contiguous blocks and improves the file access speed.
Happy with ur solution... then tick "yes" and mark as Solved!
... that is a issue with Microsoft and there operating system
And even then, only for FATx filesystems, and then only if and when you really care anymore. (As mass-storage devices become semiconductor based, you won't care anymore...) Microsoft's later filesystems like NTFS have better space-allocation mechanisms, and disk drives and controllers are considerably smarter and faster.
On a drive that had been intensively used for 8 years, fsck revealed 14% non-contiguous files. A check on the web shows people saying that you needed to defrag a Windows drive if that figure gets to 35%. Is your data ominous? Frankly, I can't make much sense of the program output!
