They are shit, not Linux.

“Not folders, but catalogues” – because there are many catalogues, but you have one folder. Usually by the word "mappings" detect ventuzyatnikov and dualbutchikov, true linuxoids... called "catalogues", and will never miss the chance to correct ignorance.

The usual red-eyed way to get out of your elitism. I saw that kind of penguin on Laura. “Catalogue” is the actual structure of the tree, “mapping” is the structure in the interface. To a virtual directory (for example, referring to a network device) the program can blindly refer to the real and see the files in it, not knowing about its "virtuality", and a virtual folder of the type "remove your computer" can only be seen with your eyes. In one manager it is (Mastday default), in another it is not (Total Commander, Norton, Lightning), because it is virtual. The /dev folder will be in any manager because it is real, although it corresponds to a virtual (AKA “special”) directory. The catalog can be mounted somewhere high in the tree, from this will change the actual structure, there will be a real path to the files. A folder that has made a quick link in the file manager does not change the actual structure of the assembly. The word “mapping” is officially used in the script because it is a file manager. It takes the directories and shows the user the folders. Apparently, the "true" Linux is considered to be the one who screams louder, not the one who co-wrote the penguin axes and their basic envelope.
