The only data a customer has for an old injection mold are these .cmp files. I am almost certain that they are script for making at least 2d drawings due to the file name being “sheet 1-10” but i have never had to deal with this. Can anyone give me some help please.
This looks like the most likely source of those files.
Apparently it was a predecessor format of .zip
You might see if double clicking on one of them in Windows File Explorer opens it (based on the link’s claim that the Windows Compression Library opens it.) Presumably if you can uncompress them they will contain a recognizable CAD file format, maybe old Autocad. Of course they might just also be password protected.
Otherwise you might post one here so interested old-timers might experiment.
