I have two different types of files on my desktop for connecting to AS400.  One is an edp file created by opening attachmate and selectiong create new session.  The other is a .ws file created by using the IBM session manager.  Both get me into  the system.

What is the difference between these two session configurations and why would I choose one over the other?

You already said it - the edp file is a profile for an Attachmate product - I know Attachmate Extra! uses them.  That's a third party package (not written or supported by IBM) that you purchase and install.  Some of Attachmate's products also support connectivity to non-AS/400 systems, like IBM mainframes, Unix, etc.  I've used various Attachmate products from time to time over the years, but not enough to provide comparative benefit analysis - I bet someone from their sales team could, though.  You could also just look through their product literature and get a feel for the capabilities of the product.

The WS file is most likely is used by the Emulator component of IBM i Access (or iSeries access, or AS/400 Access).  This is IBM software that usually comes with your AS/400, iSeries, IBM i when you purchase it.  It is licensed software and there is a cost.  Client Access is AS/400-centric, and includes a terminal emulator component, database drivers (ODBC, OLEDB, ADO.NET), the Navigator component that provides a GUI for many AS/400 operational tasks, data transfer tools, Excel data access plug-ins for accessing AS/400 data, and other features in addition to terminal emulation:

Why do you have two packages that do basically the same thing - at least as far as the AS/400 is concerned?  Who knows.  

You'd probably have to find someone around there that knows the history of the system, the emulators of choice, and/or the PC that you are using.

Maybe your company has switched over from one to the other, or is in the middle of a migration.  Maybe someone had Client Access installed and needed to access a non-AS/400 system and installed an Attachmate product.  Maybe one or the other was installed for testing or evaluation purposes.  Maybe there was an acquisition and one company was standardized on one product and the other company was on the other.

I've been in plenty of client shops where there were multiple emulators installed - for all of the reasons above.
