Azure File Sync

The Azure File Sync agent v14.1 is being flighted to servers which are configured to automatically update when a new version becomes available or manually download the update from the Microsoft Update Catalog. This is a minor release so we have some bugfix:

    • This issue occurs because the DeleteFile API on Windows Server 2022 uses the FILE_DISPOSITION_INFORMATION_EX class to delete files. The v14.1 release adds support for detecting tiered files deleted using the FILE_DISPOSITION_INFORMATION_EX class.
