sourcepak is a Rust crate that provides support for working with VPK (Valve Pak) files. It allows you to read and write VPK files, as well as extract and pack their contents.

• Read and write VPK files
• Extract files from VPK archives
• Optionally memory-map archive files for faster speeds (with the mem-map feature)
• Write VPK directory files (dir.vpk)

• Read directory files
• Read file contents
• Write VPK directories

• Read directory files

• Write VPK directories

• Read directory files

I originally created the TFVPKTool TypeScript library to support reading Respawn VPK files, along with Harmony VPK Tool using Electron.

I very quickly noticed the issue that these often resulted in high memory use due to language and ecosystem I had used.

With sourcepak I am aiming to fix that.
