Using autorun.inf to open explorer window
 

I have a simple autorun.inf file in the root directory of my PSP, set to show a PSP icon, and applying a label to it like so:

[autorun]
icon=psp.ico
label=PSPrime

Now what entry can I put in there so that everytime I go into USB mode on my PSP it launches an explorer window? Would open=explorer.exe do it?

why not just right-click on the psp icon in my computer, select the auto play tab and then select open folder to view files?
