Pre-deploy Functions

[joelaabad-cmyk]

I am new to this discussion board. If this been asked before, please direct me to the right thread. Thank you.

Is there a way to clear the deploy folder first before the actual deploy? If Yes, how can I achieve that?
How can I create a branch folder under my set deploy folder and let the extension deploy there instead.
Ex.
My deploy folder is set as "/home/job/projects"
When, I am working at branch IBM1_project1, I want the extension to deploy to create a folder IBM1 in /home/job/projects and deploy there.
When I am working at branch IBM2_project2, I want it to create/use IBM2
I could be working on multiple projects at the same time, and it would be helpful if I don't need to change any settings whenever I switch from one project to another.

Appreciate.
