Idea Configuration Files Question

All -

Can you point me to any documentation regarding Idea's use and management of its configuration files? I'd like to know, for each configuration file, its:

• name

• function

• general description of structure and content

Here is the specific problem I am having:

I am working on a product and have a main directory which is my build root:

d:\release\v72\the-product-name

I have multiple directory trees for the product, for different versions,date snapshots, etc. In order to eliminate the need to change configuration files and my typing habits, I just change the directory tree's name to the-product-name when it is the one I want to work on. For example, I may have:

d:\release\v72\the-product-name-1
d:\release\v72\the-product-name (was the-product-name-2)
d:\release\v72\the-product-name-3

If I want to work on tree #3, I do from the d:\release\v72 directory:

mv the-product-name the-product-name-2
mv the-product-name-3 the-product-name

The configurations for some of these trees are identical, and for others are only slightly different. I don't want to have to go through the UI to create a new project configuration with each new directory tree.

How can I do this?

Thanks,
Keith
