Renaming NX files from Windows

Submitted by nahidmubin on Sat, 10/07/2023 - 11:41

Forums:

I have developed a program in python that will rename the NX files from Windows and update the links between the renamed file and its parents. I am providing the python source code below. But for more info about the program and to get the executable files visit program's github page Siemens NX File Renaming .

You can also check this Renaming NX files from Windows video tutorial to see how the program works.

Source Code:
