These were actual questions I had when I worked in the computer lab. One person didn’t understand why their history wasn’t saved when they quit out of Photoshop and reopened their file. The other one didn’t understand the concept of copying pictures from disk to disk. They seriously thought that they had to go to Photoshop, select the file from the “Open” menu, then go to “Save As” and resave to the disk they wanted to copy to. I tried very hard to explain how to copy a file without laughing or crying. I often wondered what my facial expressions are like when explaining something like this.
