Anything wrong with using subst.exe?
Anything wrong with using subst.exe to remap your usb drive letter (which may change) to a consistant drive letter (like u:)? This way the apps that need absolute paths in their config files will always find themselves at U:\PortableApps\.
I realize it might not be in the true spirt of Portable Apps, but it would solve a couple headaches of mine. (Tillian and skins for a couple media players come to mind)
So, any drawbacks? I realize you'll end up with two drive letters for the USB. Also, if the target computer already has a U:, the command will fail. I'm not saying this would work for everyone, but I think it will work for me. I use my USB and PortableApps to have a consistant experience between my two desks at work, my laptop and my computer. I just dont want to go down this path if there are some other issues with subst.exe that I'm not thinking of.
