Right click on the C:\MVS folder and choose "New folder"
Give the new folder a 3 character name (all lower case) of the customer's abbreviation as shown in the MVS unix server site file field 19. Custom ext. Example: H.L. Claeys would be hlc.

Click the Add... button
Enter the company group name to the "Enter the object names to select" box and click the "Check Names" button.
If it finds the group correctly it will redisplay it with the server name prepended. Click OK.
Give full control permission to the customer's group and Click OK
Also add these users to the folder with full control permissions:
MVSoft, Administrators
I think the Users group was already added (it should not have write permissions)
