Properties show used space, but cannot access it. HELP ME!

While open it shows an empty page, no FILES! I was transferring files from another laptop and drive into mine just fine last night and now I cant get it to work. I plugged into desktop at my office and it installed drivers automatically and when i opened it i saw all folders change from folder icons to litte windows with blue borders kinda like application icons. [Deleted] IS THE PROBLEM. I cant access anything or even view files… :frowning:

Hi there, what if you try a free recovery software like TestDisk, PhotoRec or Recuva first?
