Root [International] cannot load Unlock_code.bin

[WolfieBoy]

Hey. I'm trying to unlock the bootloader on my HTC One. I have followed the instructions on htcdev.com but when it came to downloading the .bin file and using the "fastboot flash unlocktoken Unlock_code.bin" command I was asked to put into cmd I get this error "cannot load 'Unlock_code.bin'
Please help
Thanks

Hey never mind. I sorted it. I opened cmd from the fastboot folder (shift+right click then press open command prompt here).
