How it works​

The program will remove VMF parameters that have default values. When launched, Hammer will fill the missing parameters with default values; nothing changes, hence lossless optimization.

Since saving the file will re-add the default values again, the tool is best used for archival purposes. (if you're like me and have a lot of vmfs of your previous map verisons, this tool will be useful)

This program is open-source. (GitHub)

Instruction​

1. Launch vmfoptimizer.exe.
2. Drop your .vmf file into the command window. Make sure that your folder/file name doesn't contain whitespace characters or quotation marks.
3. After several seconds, the optimized vmf will be created in the same directory as the original file. The original file will still be available.
