Problem: I needed to serve a large .iso file out to my son who was in another city in his college dorm. I didn't want to drive 100 miles round trip to give him the DVD. I would have used ftp and forwarded port 21 to my internal server address but my server is already using ftp for Joomla and it's pointing to my C:\ drive for it's doc root. My C:\ drive has too little space available and so I couldn't really move the actual .iso file under C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\downloads. I do have enough space on my E:\ drive so I needed to create a link in my htdocs/downloads directory to the file sitting on E:\. I tried futzing around with Apache's Alias module and after too much time spent trying to get it to work I eventually looked for a Windows equivalent to a symbolic link.

Solution: C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\downloads>mklink visual_studio_08.iso.gz E:\vis_stud\vis_stud_08.iso.gz
