I am trying to conduct a file transfer using a USB cable. I want to send a large file to a laptop so that I can do a FULL restore on my computer. I will then send the file back to my system after the restore. I have the two PCs hooked up to eachother with the USB cable and the connection seems to be ok. Here's the problem, neither of the computers will recognize the connection and nothing happens. Do I need some kind of software? I've tried a basic file transferring program but I couldn't get it to work. I NEED this to work! This is the ONLY way to backup my files.
