To be fair, the three-letter directories aren’t particularly intuitive. “Bin”? Like the “Recycle Bin”? Or is it short for “Binary” files? But isn’t everything on the computer stored in binary? Is “dev” for developers? Is “run” for running programs? Is “opt” for options? What is “ect” even for, files that can’t find another home? In Windows, the folder names make sense and have complete sentences like “Program Files” and “Users”. I can understand someone wanting to replicate the same thing on Linux.
