>Do most developers put their app's directory under the VFP tree so they can use HOME() + "/myapp/" or what? If you want to allow the client to install your app wherever they please what is the directory and pathing scheme you should use in development?

I doubt anyone does. I also wouldn't use the Home() function in a production app. If your running from an EXE, the DEFAULT directory will be from where the EXE is running, and you should never have to give a FULLPATH from there, just relatives.
