Get path of running patch

I am sure this has been asked before (or something similar) but I can't find a dedicated search for this forum, anyway...

I want to load some audio files into a buffer without having to open a folder dialogue and selecting the folder and without having to hard code an absolute path.

I have tried just assuming [folder] would accept a relative path but that doesn't work.
Is there some way I get get the absolute path of the folder the patcher is running in?

Thanks
