How to get the id of a folder category

[Most.Ridiculous.Signup.Form.Ever.]

Hi,

I need to script the creation of new folders in Vault.  For this I understand I'm to use  the AddFolderWithCategory( name, parent, isLib, categoryId ) method.

I can't find the categoryId that would apply to create a folder of type "Project"

What method should I use to get an iterable object of folder types each containing, presumably, a possible categoryId to feed as the fourth parameter to the  AddFolderWithCategory( ,,, categoryId ) method?

Suggestion: why is the ID not visible in the human-readable properties of categories?  I could easily hard-code this, but I can't even find what to hard-code.

Thanks!

I've found clues that lead to the answer.

Turns out the EntityClassId value for the 'Folder' Entity type is "FLDR". 

This is explained in the VaultAPI.chm under the "Entities and Behaviors" topic.

It's ironic that Vault uses INT64 space for its IDs, but uses "FLDR" as opposed to the more literate and wholly logical "FOLDER" for this entity type.  

I'm leaving this here because when people search for "Folder" and "Entity Type" it can be a long slog througn a crapton of bum-steers until, finally, this comes to light.  At least that was the case for me.
