# Avogadro cannot open the save files it saved

I believe this to be a bug with Avogadro

Operating system and version: Ubuntu 20.04

## Actual Behavior

Avogadro cannot open the files gives error no molecule node found

## Steps to Reproduce

Saving the file and opening the file

I don’t know why it has a CML extension - this is a CJSON file. If you change the extension to aa.cjson, you should be fine.

Can you tell me how you saved it (i.e., why it has a CML extension)?

Sorry was a little busy didn’t see the reply actually I just did a save as and saved it in the default CML format
