Are you symbolically linking 'bin' to "Program Files", or were you just explaining what 'bin' is, for conformist Windows-using lemmings like myself?
Yes, symlinking here. I started doing this many years ago to bypass using directory name with spaces. Can you name a few programs that suggest you install directly to C:\ because of all the command line nonsense? Additionally, the new name is less typing than "Program Files (x86)". Eventually I needed to use apache, php, and other linux stuff on my machine, and it just made sense to mirror a typical linux filesystem. This current iteration is experimental until I get my new machine, but it is working quite nicely.
Wait, why do I use Windows again?
