Technical Difficulties

I got this external drive so I could take my files with me to Utah, but it has this annoying program it uses and I’m not sure if the compound will let me use it because it has to download software onto the computer to work.   I’d take it back, but it’s too late.  I’d just buy another one, but it was $80 as it was and I’m broke because I can’t get a job because I have no idea when I’m leaving.  Anyone know how to fix it so it’s just a glorified flash drive?  That’s what I wanted, and that’s what they told me this was.  I hate Wal-Mart workers, I have yet to find one that knows what they’re talking about.  You think I’d learn to not listen to them and ask someone else, but the problem is there IS no one else x.x
