Import Project Files

I am a “very” new user of the Unreal. At a local college last year I created a project and saved it to a flash drive. I just recently was able to finally purchase a new computer that has enough “horsepower” to effectively run “Unreal”. I installed Unreal on my new machine and afterward I tried transferring the saved files (summer project on the Flash Drive) to the local drive and I cannot read the project. Is there something that I am missing that is preventing me from accessing the older files?
