WinContig is a small defragmentation utility focused on individual files and folders instead of whole volumes. It is a portable Windows tool. This makes it convenient for on-demand disk optimization without a traditional installer.

Quick Start & Pro Tips
Defragment a specific game folder without touching the whole volume
- Launch WinContig.exe from your portable tools directory.
- Click File > Add items and select the game’s root folder (for example, D:\Games\SteamLibrary\steamapps\common\GameName).
- In the main list, ensure only heavily fragmented .pak, .dll, and .exe files remain checked (use the filter bar to target these extensions).
- From the menu, choose Actions > Analyze to see fragmentation details.
- Switch to Actions > Defragment and enable the option to Skip files in use to avoid conflicts with running launchers.
- After completion, export the report via File > Save list as >.txt for future comparison.
Why: Targeting only high-impact assets like large .pak or .dll files reduces disk head movement where it matters most, improving load times without the overhead of a full-volume defrag pass.
Create a reusable profile for frequently defragmented virtual machines
- Start WinContig and go to File > New profile.
- Add your VM disks (for example, .vhdx, .vmdk) using File > Add items, pointing to your VMs storage folder.
- In Options > Settings > General, enable Save last file list on exit so your VM set persists between sessions.
- Save the configuration via File > Save profile as and store the .cfg in the same folder as your VM images.
- For each maintenance window, open WinContig, load the profile with File > Open profile, then run Actions > Analyze followed by Actions > Defragment on the VM files only.
Why: Virtual disk images grow fragmented quickly. A reusable profile lets you defragment only .vhdx or .vmdk containers on a schedule, improving sequential I/O performance for guest OS workloads without touching unrelated data.
Use filter rules to avoid defragmenting log and cache files
- Open WinContig and choose Options > Settings > Filters.
- Add exclude patterns for volatile files, such as *.log, *.tmp, and browser cache paths (for example, C:\Users\%USERNAME%\AppData\Local\Temp\*).
- Save your configuration and confirm that the main file list hides entries matching these masks.
- When you run Actions > Analyze and Actions > Defragment, verify that only stable data assets (like .iso, .mkv, .iso, or project .psd files) are processed.
Why: Excluding high-churn data like .log and temp files prevents wasted work on files that are constantly rewritten, focusing defragmentation on large, read-heavy assets where contiguous layout has the biggest impact on throughput.

Notable Features
- Targeted file and folder defragmentation: WinContig focuses on defragmenting selected files and folders instead of entire drives. This is useful when you want to optimize specific game assets, virtual machines, or large media files without running a full-volume defrag.
- Portable, no installation required: The tool is distributed as a portable executable, so you can run it from a USB stick or a tools folder without modifying system settings or adding entries to the Windows registry.
- Custom profiles and filters: You can group sets of files into profiles, apply include/exclude filters, and run defragmentation on these predefined groups for repeatable disk optimization workflows.
- Integration with Windows shell: Optional context-menu integration lets you launch WinContig against selected files or folders directly from File Explorer for faster access during routine maintenance.
