WinContig is an easy-to-use stand-alone defragmentation tool that doesn't create any installation directories or Registry entries on your computer. Its purpose is to quick defragment files without the need to defragment the whole disk. WinContig supports FAT32 and NTFS file systems and it works with Hard Disks and SSDs.

Most defragmentation programs perform a general defragmentation of an entire partition. In a real-life scenario, you often want to defragment a single file or a directory, for example to improve the loading speed of a program file, or to reduce the loading time of a certain disk intensive application like a game.

WinContig has been designed specifically to meet the needs of users who focus mainly on files and folders rather than an entire disk.

Its ability to filter files by several criteria combined with its ability to be controlled via command-line switches, make WinContig the perfect tool to defragment particular files that are frequently used and continuously becoming fragmented.
