Why are there so many CXL and MTD files?

If you use Windows Explorer to find your model files, you will also see many other files.

Why so many? They are the backup files.

The CXL is the file that you open to open MechDesigner model. The MTD file - the motion in MotionDesigner - will also open automatically.

When you open a model, we also look for the oldest backup files and copy them to another backup file.

CXL.n and MTD.n are copied to CXL.n+1 and MTD.n+1

Thus if:

1.CXL.2 and MTD.2 are the oldest, they are copied to CXL.3 and MTD.3

1.CXL.1 and MTD.1 are copied to replace CXL.2 and MTD.2

2.CXL and MTD are copied to CXL.1 and MTD.1

3.A copy of CXL and MTD are saved to RAM


When you Enable Auto-save, we auto-save the model, after a number of commands:

1.CXL and MTD in RAM are saved to ~CXL and ~MTD on disk

2.New copies of CXL and MTD are saved to RAM

WARNING : You overwrite the original model with each Auto-Save.

See Application Settings > General tab > File Options to:

Enable or disable Auto-save
