WinContig is a simple free defrag tool that can be used to quickly defragment files without defragmenting the entire disk. This tool can even defrag ISO files. The creator designed it to have the ability to defragment folders or even single files without having to defrag a whole drive or partition.
Advanced users will like that it accepts a number of optional command line switches that can be used to manipulate how the portable defragmenter operates. You can also group files into profiles. This defragmentation tool is a standalone executable that doesn't require installation and doesn't create any registry entries on your computer.
