    1. Click Get List of Projects to first fetch the list of projects.

    2. The status of the Get Projects action is logged in the Extraction Job Status table at the bottom of the Settings page.

    3. Once the folder synchronization is successful, a drop-down list of projects will become enabled. Select the projects you want to extract.

    4. Check if you are using the desired filter option. Available filter options are described below:

    Filter Option
