Oh my DM really leaned into that one. Had us searching for a golden brassiere as part of a ritual we needed to perform. We ended up picking up a rumour that the captain of the guard wears one, so on to the seduction attempt to go find out what she’s into and where she hangs out. Play through the whole bit, get the brassiere and then ask what we do next. Well, now we need to burn incense in the brassiere. Now everyone just looks at eachother completely confused. Then the guy sitting next to the DM suddenly perks up and asks to see the module we’re running for a sec. Tells the table it says brazier. Confusion dispelled and everyone laughing for days.
It was called spanning and was usually done with a third party utility like xcopy or pkzip, but I am pretty sure MS backup did it as well. I don’t think you could do it with DOS copy command through v6.22.
