You can export list of forms from Developer studio either you can do the same from sql management studio by running a query select *from arschema this will let you know the all form names with their schema id and nextID.
There are a number of ways to do this. If you have access to the database then this SQL will list the form names
> select name from arschema order by name
Or you could use the reporting feature in AR against the AR System Metadata: arschema form.
Beware that some forms use aliases - Incidents is the alias for the form named HPD:Help Desk for example.
