How to get RQM Project Path

How I understood your scenario is that you have some of the file in to RQM PROJECT? I have not understood where in RQM PROJECT path you have those files or there references. If you are mentioning about some of the files attached to your RQM Artifacts ( such as Test Case ) then I think you may have to find the URL ( not the shared location) of that attachment to fetch the file on your local machine via your script. Any way I am assuming too much here and would need some more information from your side. 

Could you please explain more about which types of files part of RQM Project which you scripts makes reference to?

However - you are correct about the fact that if network shared location is used then scripts are copied to the machine local to the adapter ( where adapter is running ). And if you mean files in project by Attachments to RQM Artifacts and if you running a command line adapter then - you can use execution variables to pass on the URI of the attachment you want to your functional scripts to use. These URIs can be used to download the attachment ( via REST get on those URI through your Scripts ) on local machine where adapter is running via your scripts and then these files could be used. 

Thanks,
