Documentation/Tools/Game Archive Packer

The ETS2/ATS update 1.50 introduces a v2 version of HashFS format. This format allows for more efficient loading of game data by storing resource metadata in memory. While all previous formats are still supported for mods, they might cause stalls for some resource types as the engine assumes that the metadata are available immediately. This tool provides support for creating and extracting .scs pack files. The creation supports v2 only, extraction supports both v1 and v2. The previous extraction-only variant with simplified interface is still available Documentation.

Please note that there might be some changes to the format during the 1.50 beta.

Archive extraction

To extract the content into the current directory use

scs_packer extract archive.scs

To extract the content into a specific directory use

scs_packer extract archive.scs -root <directory>

Archive creation

To create archive from content of specified directory use.

scs_packer create archive.scs -root <directory>

The tool will automatically compress all compatible files. For development purposes it might be useful to disable the compression by specifying -nocompress parameter to speed up the entire process.
