How can I find orphaned files in the Vault?

Hi Chris, Thanks for the fast answer and the code sample! I didn´t know about the FileContainerLocator. Finally I think I understand what the File_Handling.pdf provided in the Documentation folder want´s to tell me. Now let´s see if I get things right: 1. Regular files referred to ECOs, Documents, etc. -> no container assigned 2. Regular files removed from ECOs, Documents -> Orphaned Files Container -> can be automatically deleted when using the Force.Delete.Orphaned.Files Variable 3. Thumbnails, Files created by conversion server or any other files without container -> Global Files Container I wonder what´s the best way to clean up historic conversion server files? The files are easy to detect, as they all share a similar checkout path. But I do not think it´s good idea to remove them automatically. Do you have any recommendations? Right now the amount of Converser Server files is no problem, so this is more a question of "how to do things the correct way".
