32 bits update 64

Storage Location: I’m currently using Orthanc 32-bit on Windows with MySQL as the back-end.
Could you confirm whether the DICOM instances are stored as BLOB fields directly inside the orthanc_db MySQL database or as physical files in the OrthancStorage folder by default?

Backup/Restore: If I back-up and later restore the MySQL database (orthanc_db), will the images be restored as well, or do I need to restore a specific folder on the file system?

Scenario: After upgrading to Orthanc 64-bit (Win64-25.12.3) and keeping the previous JSON configuration files, the study list appears empty.
What could have caused this? For example, could it be a path-configuration issue in the JSON file, or might the MySQL plugin have failed to load and Orthanc fell back to an empty SQLite database?

How can I verify which plug-ins are actually loaded and whether Orthanc is pointing to the correct storage location?

You can check the list of loaded plugins in t…
