Hello,
So far, the DICOM/ZIP files are named according to the identifiers that are used by Orthanc to identify the corresponding resources.
If you need control over this filename, you will have to implement a custom C/C++ plugin that:
- Installs a REST callback with "OrthancPluginRegisterRestCallback()"
- Downloads the DICOM/ZIP through "OrthancPluginRestApiGet()" into a memory buffer inside this callback
- Sets the HTTP header "Content-Disposition" to the value "filename=MyFileName.zip", through "OrthancPluginSetHttpHeader()"
- Outputs the buffer downloaded at step (2) using "OrthancPluginAnswerBuffer()"
HTH,
Sébastien-
