fscommand
I posted a few days ago about access to the file system via the Flash projector. I discovered a built in ActionScript function called fscommand. Apparently Flash projectors (pre MX) can execute files on absolute or relative paths; however, in MX, Macromedia decided it was necessary to restrict access to the file system to prevent liabilities. You can still launch executables in the Flash projector as long as the executable resides in a subdirectory called fscommand. It's kind of annoying, but good enough to meet my needs. I thought I'd pass the info along to anyone else that might be trying to accomplish a similar task:
fscommand("exec", "filename.exe")
