SysInternals – Contig

Along the same lines as PageDefrag is Contig. Contig is a command line utility that will allow you to defrag a single file or group of files, instead of having to defragment your entire disk. Here’s the command line help:

Contig v1.53 - Makes files contiguous
Copyright (C) 1998-2006 Mark Russinovich Sysinternals - http://www.sysinternals.com

Contig is a utility that relies on NT's built-in defragging support to make a specified file contiguous on disk. Use it to optimize execution of your frequently used files.
Usage:
contig [-v] [-a] [-s] [-q] [existing file]
or contig [-v] -n [new file] [new file length]
-v: Verbose
-a: Analyze fragmentation
-q: Quiet mode
-s: Recurse subdirectories

Usage is pretty simple, just type in Contig followed by the file (or file spec, such as *.mdb) you wish to defragment. This can be useful if you have some larger database files or other files to process that are running slowly. Use contig prior to running your large jobs and you’ll see a nice speed boost.

Also useful if you just want to see if your file is fragmented, just add the –a switch prior to the file name and it will tell you how many pieces your file is fragmented into.

Note, with all these tools you use at your own risk. Always make sure to backup important files prior to running any of these tools on them.
