UnmountOnTermination Property

Whether the virtual drive should be unmounted if the application terminates. (Windows only).


bool GetUnmountOnTermination();
int SetUnmountOnTermination(bool bUnmountOnTermination);

Default Value



This property specifies whether the CBFS Storage driver should automatically unmount the virtual drive (closing all handles and other resources associated with it) if the application terminates.

If this property is disabled, applications may need to call the ForceUnmount method after a crash (if there was a file-based vault open and mounted as a virtual drive when the crash occurred).

Note: This property cannot be disabled on non-Windows platforms.
