I strongly belief that Mentor PADS 9.x.y...VX.x.y does _not_ rely on the file extension to work correctly. However it makes loading of the file more simple as file dialogs ask for ".asc" or ".txt".
The header / first lines look important - i.e.: Netlist: !PADS-POWERPCB-V9.0-METRIC! NETLIST FILE FROM PADS LOGIC VVX.1.2 *REMARK* P1234-XYZ-2.3.4.sch -- Fri May 06 11:56:49 2017 *REMARK* *PART* ITEMS J1 CON-SAM-FT5-RA-30@CON-SAM-FT5-RA-30 X1 MTG-340-600@MTG-340-600 C1 C-3216M-N/A@C-3216M C67 C-1005M-103-25V-X7R@C-1005M ...
