Want to change default install folder away from Documents

As you guys are probably aware, when installing certain programs, some folders get created in the root of the Documents folder. I don't like how these mix with my actual documents. So I'd like to do either of these things:

Either change the name of the Documents folder (I'd name it Programs) and then I'll just create a new Documents folder under Users and use that for storing my files

Or change the default location where these folders get created (So I'd create a new folder called Programs and change the location to that folder)

Thanks!

Each such program usually has a setting in Preferences, Options or other place to specify where documents created in them can be stored by default but you have to make the change in each one.
