Hi Laura GEELHOED,
Thank you for reaching out to Microsoft Q&A forum.
To save your work on the VM during the Exercise: Create calculation groups Training, you can follow these steps:
1.Save any files you're working on directly to the VM's file system. This ensures that your work is stored on the VM itself.
2.Consider utilizing version control systems like Git when coding to push changes to a remote repository, safeguarding your work against potential loss due to VM resets.
3.Before ending your session, export data from the VM and import it when starting a new session if working with datasets.
By following these steps, you can ensure that your work is saved on the VM and easily accessible even if your lab time expires.
Please inform us if the problem persists, and we'll be happy to offer further assistance.
Thank you.
