Hi jimerg,
This could do done with the exiting QAP features and, for #2, some batch file coding. I'm leaving today for 2 weeks and could not elaborate on this now but here are the headlines:
1) use placeholder {Clipboard} and create a folder favorite with location "C:\Cars\{Clipboard}"
see:

- create a batch file that checks if the folder exists and creates it if it does not. The batch would receive the folder to check as parameter. Add an "Application" favorite with the location of this batch file and enter "C:\Cars\{Clipboard}" (keeping the double quotes) in the parameters field.
If you need help creating this type of batch file, maybe other users could jump in until I'm back.
Good luck.
(I'll move this thread to the "Support" section).
