Ouh, you know I was curious and it seems that I still know two at least, or I think so...
RAD, or... Rapid Application Development to store some specific project utilities like this one?
Sets, maybe someplace to store environment elements and backgrounds?
Cache, hmmm, I think I still have some doubts with this word! But it seems that I was not far worng? Or I hope so...
Well, and all thanks to Wikipedia! Although any other suggestions would be very welcomed too

, BYE!
I'm sorry I didn't see this sooner. This must be questions on the file structure I use for projects. And I guess the 'readme' file does not explain the 3 folders so here it goes:
RAD = Research and Development This is a folder were I keep my testing for, well, anything. Right now in the RAD folder of my current project are a a whole lot of folders: AfterBurner is were I worked out the sprite effects and emitters for space ship rockets; BlastWaveThroughBuildings are a mixture of AM features and plug-ins and tests for how to do this; Galaxy is the folder where keep everything on creating a particle based galaxy such as tests, forum links, tut files, etc.
Sets = This is like a movie set or a movie 'location', a Set is a collection of models that might make up a hospital room, or the cockpit of a space ship. Almost always 'sets' are kept in chor files. In most cases Sets are not maintained separately and are just part of the Scene folders but sometimes more then one Scene uses a Set or a Set is so complex that it is built outside of the Scene folder.
Cache = A place for files (usually large files) that you do not want to include in the nightly backup or, send to a person who is helping you. This has to be setup; you have the <Project Name> folder and the <Project Name>_Cache folder in the same folder. Folders in the project folder such as 'Screen Tests', 'Stills', 'Promotional', will be copied to the 'Cache' folder and linked back into the project folder. As an example in the ..\<Project Name>\Models\Actors\<Leading Male Model>\Maps\Face folder will hold the tga images used for the model's face and also a folder called wip (Work In Progress) which will contain the Photoshop files (usually huge files) I used to create the face maps. I will normally move the wip folder to the Cache folder and a link to it also called wip put in its place. Also, the Cache folder will have the same folder path to the stored folder. For instance in the above example the wip folder will be located in ..\<Project Name>_Cache\Models\Actors\<Leading Male Model>\Maps\Face\wip.
This is just the way I do it. I'm not sure that there is an industry standard -- I looked for one before creating my own and if there is one or one becomes available then I will certainly switch to that.
Cheers,
Rusty
Edit: Please keep in mind that this entire thing is something that I just made up. I needed something, couldn't find anything so I created something. If TWO had been around back then, I certainly would have looked at what TWO was using and adopted that. You might be far better served looking at what TWO is using.
