Not exactly PortableApps.com standard, but it will do...
I'm trying to make my own collection of programs whose folder structure is compatible with the PortableApps.com Platform folder architecture.
FOR EXAMPLE:
For Firefox 3 Portable,
- [DRIVE LETTER]:\
- |
- |___PortableApps\
- |
- |___FirefoxPortable\
The PortableApps Menu lists any EXE files located in the sub-folders directly within the PortableApps folder.
I've used programs from a USB drive that were not meant to be portable,
