How to save a created document to a predefined path on hard disk?

I need to do loadtesting for Indesign server.

I have a created a Document with a custom setup (10 pages etc) .I opened a layout for it and I have the DocRef for my just created document.

Now I want to save the document on a predefined path(Which I can hard code in my code) on my system(lets say in MyDocuments folder).

What command can I use to do this?
