Time Capsule as HD?!

I just bought the Time Capsule thinking I could use it as an External Hard Drive with Bootcamp (windows 7 on iMac 27) , I've been searching all the way on the internet with no luck , please help me

Additional question:

1.- Is there a way to connect the Time Capsule via Usb or something, rather than Wi-Fi?

You can use it as a network external hard disk. I.e. it needs connecting to your router by Ethernet or wifi.

The USB port cannot be used to connect directly to a PC or Mac.

If your using the time capsule for Time Machine it's likely formatted as HFS. Windows can't natively use HFS so your best creating a partition using FAT32 for windows use

No need to reformat in order for Windows to see it. In fact I don't think that is possible without removing the drive . If Windows is not seeing the Time Capsule try this. Works for me under Win 8. Also worked in XP IIRC.
