Hi Yeti, Thanks for your help. The size of the sandpaper is 25.348mm * 12.397mm. I contacted the SENSOFAR people who helped us with the measurement. They did not have a documentation about the .plux file but they mentioned that the new machine will generate both .plux file and .plu file for compatibility. Now I have got the corresponding .plu file and I can open it using Gwyddion.
If I know more information about .plux format, I will post it here. Thank you for your time.
