When I plug in a USB memory stick I get the dialogue box shown below.
Can I use the option "open folder to view files using Directory Opus" by default for all memory sticks...? The image below shows the "defaults" screen which doesn't have my memory stick listed (in the same way my Sony Walkman is listed). Does this mean I can't default it...?
If it helps, my memory stick is defaulted to the N: drive.
You may be able to put an AutoRun.ini on the memory stick, but note that Microsoft are going to disable AutoRun for removable media, except CD-ROMs, due to it being used to spread malware:
(It's already blocked in Windows 7 and they were planning to release updates which do the same on XP and Vista. Not sure if they have released them yet or not.)
