What do you mean by "doesn't"?
What happens when you try to open it?
What kind of file is it?
Is it the file that doesn't work, or the Sandisk USB thumbdrive itself?
Provide details and context about your issue, and someone may be able to help.
I would add that thumb drives are not reliable and will often fail. Not a good place to save files. Try copying the file over to your HD and try again.
Before what?
How is the thumb drive formatted?
Have you tried dragging the file to your Desktop and opening it there?
