thanks for your interest. The Example is quite simple, all i need is the functionality within the RunLink of Applications to support variables like %WINDIR% or %SYSTEM% like they do the job in each command box (CMD).
When i plug in my USB-Stick, then i register a variable like the above where the value is the root of my stick, so i am able to use this from other programs to open applications .
The other way with the relative paths is, i think the operating path of Portable Sticky Password is the USB-Drive (i think so). And then i can navigate with relative paths from there to my application from the stick like the scenario below:
Sticky Password is started from USB (f:\) so the working directory is f\:Sticky Password .
Now i want to save as RunLink the relative Path from the working directory to my Application i.e. Filezilla.
I hope my english is not to bad, so you understand what i tried to tell you.
Thanks for your effort
