Did you get an operations manual with your 2nd hand camera? If not you can get an online manual in PDF format from the various Sony web sites.
First off, I want to be clear that I'm not a Windows user, however there are similarities between platforms.
The firewire port (iLINK HDV/DV) is not for transferring files. It's only used to record HDV to another device such as an HDV camera or similar. The USB port is the only way to transfer files using the camera.
You need a Windows program to recognize the clips and to work with them. It's called Clip Browser and you can find it here:

It's free and comes with an instruction manual as well as the program. You'll find the correct software for your application on the page listed above. Look for "XDCAM Browser Ver 2.0 for Win"
And here's a link to the EX1R operation manual:

If anyone knows of a newer Clip Browser version please add to this thread.
Good Luck
