ScheduledPlugIn - how to delete unpublished/old versions of MediaData

Member since: 2010

I have some code thats gets files from a service. If a file is changed i will first update the file and after delete the old versions of this content (do this to save disk space)

When i try to delete old versions i get this error in my logs

EPiServer.Core.AccessDeniedException: Access was denied to content 13893_94956. The required access level was "Delete".

This line fails


How to fix this?

Entire code

// Will delete previous versions of pdf file
public static void DeletePreviousGenericMediaVersion(ContentReference epiFileRef)
var epiFileVersions = versionRepository.List(epiFileRef);

foreach (var epiFileVersion in epiFileVersions)
// Delete all unpublished file versjons
if (epiFileVersion.Status != VersionStatus.Published)
// Before we delete the content we need to clean up blob data on disk. To do this we need BinaryData ID
var epiFileVersjonContent = Repository.Get<MediaData>(epiFileVersion.ContentLink);

    Hey, Øyvind,

    Are you doing this from a scheduled job? Can you add the following before you start deleting:

    EPiServer.Security.PrincipalInfo.CurrentPrincipal = EPiServer.Security.PrincipalInfo.CreatePrincipal(some_admin_user_who_has_delete_rights);
