Okay, let's do a lab.
In this lab, create a directory structure TMP files,
pictures, TMP files, photos, and TMP files videos.
Copy all files that have a name starting with an A, B, or C from etc to TMP
files and from TMP files. Move all files that have a name starting with an A or B
to the TMP files, photos and files with the name starting with the C to TMP files videos.
