What is WinContig?
WinContig is an easy-to-use stand-alone defrag tool that doesn't create any installation directories or Registry entries on your computer. Its purpose is to quick defrag files without the need to defrag the whole disk. WinContig supports FAT32 and NTFS file systems and it works with Hard Disks and SSDs.
More focus on files
Most defrag programs perform a general defragmentation of an entire partition. In a real-life scenario, you often want to defrag 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 defrag particular files that are frequently used and continuously becoming fragmented.
WinContig is a standalone executable, and it doesn't require any installation process or additional DLLs. All the files required to run WinContig, including any settings, reside in a single folder.
Very fast and Reliable
Defragmentation and analysis processes are based on kernel-mode interface library functions. Thus, performing defragmentation process is safe and there is no risk of losing data.
Defragment single files
Specifically designed to defragment single files or entire folders without the need to defragment the whole disk.
Make WinContig function in a way that fits your needs.
Check disk integrity
Check disks for file system errors and get some useful information out of them.
Support for command-line switches
WinContig accepts a number of optional command-line switches that you can use to control how the program operates.
Remove unnecessary files
Delete temporary files before defragmentation.
WinContig is available in more than 25 languages thanks to the volunteers' contributions from all over the world.
WinContig is released as freeware and you can use it on as many Windows computers as desired for both personal and commercial use.
Integration with File Explorer

Frequently Asked Questions
A list of Frequently Asked Questions about WinContig submitted by users
How safe is WinContig?
Defragmentation and analysis processes are based on Windows kernel-mode interface library functions. Thus, performing defragmentation process is safe and there is no risk of losing data, even in the event of a power loss.
Can I run WinContig from within a batch file or schedule its execution?
WinContig accepts a number of optional command-line switches that you can use to control how the program operates. This let you call WinContig from within a batch file or use Windows Task Schedule to schedule its execution.
Does WinContig use Contig by SysInternals to perform the analysis/defragmentation process?
Absolutely no. WinContig is not a GUI for Sysinternals Contig, nor Contig is embedded within WinContig.
WinContig is freeware. Can I use WinContig at work?
Yes. WinContig is released as freeware and you can use it on as many Windows computers as desired for both personal and commercial use. You don't have to register or pay anything.

What is the difference between Quick Defragmentation and Smart Defragmentation?
WinContig supports two different defragmentation methods. If you choose the Quick method, WinContig does look for the first amount of free space large enough to defragment a file into and uses it. Use this defragmentation method if you use tools like Windows Defrag to defragment your hard disk on a regular basis. If you choose the Smart method, WinContig does look for the amount of free space that best fits a file into and uses it. Also, if there is no free space large enough to fully defragment a file into, WinContig does try to reduce the number of fragments of that file.
My antivirus program alerts me that WinContig is infected with a virus. Is it true?
No, that's a false positive. Every file included in the distribution package is automatically tested on VirusTotal (www.virustotal.com). We put online a new release only when all files have successfully passed most of the virus scanning engines. WinContig is 100% clean.
