Diagnosing NS_E_WMPCORE_MISNAMED_FILE
This result is HRESULT 0xC00D1099. At the playback core misnamed file checkpoint it means the file extension/name disagrees with the content or supported media interpretation; the result belongs to the WMP playback core, graph and media-resource boundary, not to an unspecified Player failure.
Evidence that separates the result
| Result | Different condition |
|---|---|
NS_E_WMPCORE_CODEC_NOT_TRUSTED | The candidate codec fails the trust/signature policy required for installation/use |
NS_E_WMPCORE_CODEC_NOT_FOUND | The graph cannot find the specific codec required for a media stream |
NS_E_WMPCORE_CODEC_DOWNLOAD_NOT_ALLOWED | The required codec is absent and Player policy/settings prohibit automatic acquisition |
Representative case: A downloaded HTML response is stored with a media extension.
