Toolkit Updates

CBFS Connect

The new NFS component implements an NFS 4.1 server, providing a simple way to mount a drive and serve files without a kernel mode driver. The NFS component is available for all supported platforms, but is particularly useful in macOS where kernel mode driver installation can be challenging.

The CBFS component has been updated to provide additional functionality including support for extended attribute operations. New API members including SetEa and QueryEa methods and the SupportExtendedAttributes property provide options to manage extended attribute operations.

Sparse file support can be enabled by setting the new SupportSparseFileAttribute property and handling the QueryCompressionInfo, QueryAllocatedRanges, and ZeroizeFileRange events. Support for compressed files has been improved and the new SupportCompressedAttribute property can be used to enable support for this attribute.

CBFS Shell

CBFS Shell includes three components to easily extend Windows Explorer with support for virtual folders and custom menus. The ShellFolder component enables creating a virtual folder containing items in the Windows Shell. The ShellMenu component enables customizing Windows context menu items and commands. The ShellNotify component enables monitoring file system change notifications.
