I found something I could make that could be useful, at least for me.
Basically a text file that has the names of each folder in TS2's Documents directory and the explanation of what each is.
This could be practical for installation instructions but also just curiosity.
I'm thinking it will be a bit of a dumb idea since you can easily search what each one is, but I intend to document even the unknown ones, although I want your feedback on this project. :D

Well, most of the folder names are self-explanatory anyway. Like, Cameras contains files that define camera behavior; Collections contains files that define collections in build/buy mode; Logs are logs etc. I suppose the main concern would be the SavedSims, LockedBins and Teleport?

Stuff like that. Yup, most are self-explanatory, so I'm planning to document some unknown ones.
There are some other stuff I wish to write about as extras for example the Bins folder in the game's files as well, not just userdata.

Hm, perhaps. It never hurts to have some more information about something!

Though, even if I knew that the Overrides folder in the game files contains overrides of game objects without marking those as custom objects, I'm not sure if I'll benefit from that information directly - personally, I only put things in the program files if the mod has specific install instructions anyway.

Yeah, that's why I'll only write about game file directories that are commonly used for custom install instructions:
Bins, Skins, and some other are used to install some specific mods.

Any update?
