Hi all,

When MaximumStorage (e.g set to 100000MB) has been met, how does Orthanc decide what studies to delete to free up space for new studies to come in?

Hi,

This is summarised here - [https://book.orthanc-server.com/faq/features.html#recycling-protection](https://book.orthanc-server.com/faq/features.html#recycling-protection)

In short, Orthanc tracks when each patient last received an instance and keeps a Recycling Order. When it comes time to free space, Orthanc will delete the oldest patients.

HTH.
