Hi Manu, The ascii files are the ones that will be easiest to import. But 9 is the latest version I think, and there were lots of changes. I am not sure since I don't use anything that new. But even using files between versions of PADS it's pretty much always been required to use the ascii files. One final confusion is that sometimes the .asc suffix has been used for forward-back annotation etc. So it may not even be a schematic, just a partial netlist. Your best hope is to find someone with PADS 9, open the binary (pcb, sch) files, and then export them. There is a guy I hire once in a while who could do it but he has a half day minimum.
