Eh.. i thought i was pretty brilliant in computer Os's, runing a small computer repair service out of the house, working at a Computer consultant, but today ive been stummped. My sister is in college and is taking a technology course (should be simple, not for super geeks) and has these questions for her final.. i dont know any but one how can you show file extentions? what appears on the task bar what happens to files that are deleted from an external drive? What happens to files deleted from the hard drive? I am guessing it is talking about the windows os, but i could be wrong... If anyone knows the answers please respond!
