As @Daniel_Catalina has told you, everything should be in that Rawpedia page.
Anyway, to my knowledge RT doesn’t mind about the OS you’re using, so adding «/» to point to a subfolder is the same as adding «\». Take a look at this relevant post, where you can see an example for Windows paths.
As an example to your doubt, if you want your queue exported files to be placed in a subfolder called «converted», inside the folder where your raws are (that is, the default output folder), but the name ending in «_RT», in the queue Use template field you would write:
%p1/converted/%f_RT
However, following the example in that other post, if you want to export to another specific, not RT related folder, you would write:
c:/your/export/destination/folder/%f_RT
Of course, the drive letter should be the appropriate one, and the slashes could be written reversed (\) if you wish.
