Some of the files under the WDIR (for example: user.cns) are not compatible with all versions of SDD (EE/BSXE/PADS/IND) Flow software, and in some cases can actually cause applications to crash.

With this setup in place, every time you run the Configurator to switch versions the WDIR will change to the appropriate release-specific folder.
For more details and other WDIR switching techniques, refer to pages 98-104 of the attached Managing Mentor Graphics Systems Software (EE7.9.5) manual.
