Files and Folders
By the end you can say what a drive, a folder, a path and a search are and read a path aloud, build the BootCamp tree on your own machine and say where any piece of programme work goes, fetch the week's course files from Mufasa into it, name a file so it sorts itself, test an AI's naming rule against the poster, copy the tree to a second place, delete a file on purpose and bring it back, and find any named file in under a minute.
