1. Both DriveWorks Solo and DriveWorks Pro can save files into custom directories. With DriveWorks Pro you can integrate with EPDM and WPDM
2. Unfortunately custom configurations cannot be captured. please see our help file for more information - http://docs.driveworkspro.com/Topic/HowToSolidWorksBestPracticesConfigurationSpecificProps
3. This is again possible in both DriveWorks Solo and DriveWorks Pro. A File Name rule simply requires "*" & before the rule to indicate that the original name should be removed.
My advise would be to download DriveWorks Solo on the 30 day free trial. You can go through the training material provided free of charge and evaluate for yourself whether Solo is the right product for you. http://www.driveworkssolo.com/index.php/try-it
If you would like more information on DriveWorks Pro, then I would suggest talking to your SolidWorks Reseller and asking for a demonstration. or by going to - http://www.driveworkspro.com/index.php/what-is-pro
Let me know if you have any further questions
