What is WinContig?

More focus on files
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.
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.

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.
