Need help to understand how i can proceed

I recently begin create mods whit the ark dev kit. i keep ask google and other forum this question : How i can create a sub folder like it is organised into the smithy or into you crafting inventories. My goal is to to create a bookshelf whit an automatic and predefined organisation.

I also wan know how the qualities system work i wan work whit this aspect. For the moment it seem to be randomized. if i rote a command line ex : give itemnum 1 (who is the pistol) 1 (who is the quantities) x who is the qualities (primitive/ramshackle and etc.) 1 who is a blueprint instead of 0 who is the item. what does x need to be to be a definite qualities?
