Hi I saved a large number of files (7000 - I'm a teacher) to my USB stick from my work computer (Windows). Today I put the USB stick in my Mac and saw only a black rectangle with the name of the USB stick and I couldn't open any files. I returned the stick to a Windows computer and found that the files had disappeared and in their place was a 'shortcut' to the files which didn't work. I put the stick in another Windows computer and first ran a virus check before opening it. The virus checker checked all the files, even naming them. But still I can't access them. Are the files lost or is there another way of finding them? They are no longer on my work computer so really hoping there is! Many thanks in advance!
