Problem with encrypted PDF and DOCX-files

Dear team,
i am using GroupDocs Viewer DLL 18.4 with
When using GD_handler.GetDocumentInfo and GD_handler.GetPdfFile on encrpyted pdf and docx files I get a PasswordProtectedFileException (as far as I know there is no way to get the encryptions status of a file). After this the pdf/docx-file is blocked by the GroupDocs process, so I cannot rename or delete this file. Is there a way to release the files?
Thanks in advance!
