Problem transferring data via flashdrive

I am in the process of moving to a different computer. The one I had before is a laptop ASUS with Windows 7 Ultimate 32 bit. The one I'm transferring to is a Windows 7 Ultimate 64 bit. I copied a very large folder onto a 32 gig flashdrive, put it in the new computer & it did not show. Other smaller files did show, but not this one. The flashdrive shows the space being used. How do I get the file on my new computer?

Dear Ranger4

Thanks for your concern, but I figured out why I couldn't get the file to transfer. The hidden button on the properties was checked! I don't know how it got that way. But that was the problem. My next problem, however, is that I tried to download some of my old files I had in the old computer & it got me Cassiopesa as a web page. That's an adware thing. It hijacks your browser & you can't get rid of it even with some adware cleaners. Do you know of any FREE programs that will get rid of this?

Thanks, Q40
