Methods
The IZoneIdentifier2 interface has these methods.
| Method | Description |
|---|---|
| GetAppDefinedZoneId | Gets the app-defined zone ID set by the last writer. |
| GetLastWriterPackageFamilyName | Gets the LastWriterPackageFamilyName for the last Store App to write the file. |
| RemoveAppDefinedZoneId | Removes the AppDefinedZoneId, effectively resetting it to the system default. |
| RemoveLastWriterPackageFamilyName | Removes the LastWriterPackageFamilyName from the Zone.Identifier alternate data stream. |
| SetAppDefinedZoneId | Sets AppDefinedZoneId to the ZoneId hint specified by the app. An app can update this field only if the file is open for read/write access; this will also update the LastWriterPackageFamilyName. |
| SetLastWriterPackageFamilyName | Sets the LastWriterPackageFamilyName of the last Store App to write the file. If the existing last writer is different from the current writer, AppDefinedZoneId is cleared. |
