Hi Jean,

Thank you for your question.

When you enable the 'Subscribe' option, you will get any file updates for this metadata type.

This means that each time when you pull files from your Salesforce org, the newly created on SF files in the metadata you subscribed for will be downloaded automatically or removed if they are deleted on your Organization.

In general, you will have the actual state of all the files inside the subscribed metadata after each pull from Salesforce.

If you have any additional questions, please ask us. We will be glad to answer them.

Regards,

Kate
