Thanks Steve, that was it. Regards, Djula > I've recieved some PCB and SCH files, but I can't get in touch > with the > sender. The extensions are DDF and SCH and the files are textual. Does > anyone know what program can open these? UltiBoard uses a text file with a DDF extension for PCB and SCH for schematic. The DDF file shoulp start with a "*" and "P" followed by the customer name and the next line has the version and revision number. Someone bought someone else and Ultiboard is now supplied with the Electronic Workbench product so that may be able to read the file. http://www.ultiboard.com Be warned - I found the product to be unreliable (disconnects parts of nets etc) and support was empty promises and large bills. YMMV.
