PDF wasn't much help, just to make sure we're talking about the same one: SINS_modset.pdf?
yes
i don't see how that could not be help
Once you have completed creating or editing any Sins text data
files you may want to convert them into binary to speed up load
times. This can be done by using the provided command line tool
“ConvertData.exe” .
The syntax is
convertdata
The valid types are: mesh, particle, brushes and entity.
Example:
convertdata mesh mymesh_text.mesh mymesh_binary.mesh
what about that is unclear?
edit: oh i get it. you can't double click it. run it from the command line.
