Whether the virtual filesystem supports alternate data streams.
int SetUseAlternateDataStreams(int bUseAlternateDataStreams);
INT SetUseAlternateDataStreams(BOOL bUseAlternateDataStreams);
This property specifies whether the virtual filesystem should indicate to the system that it supports alternate data streams (ADS, otherwise known as "named streams"). Alternate data streams can be present in both files and directories.
If this property is enabled, the application must properly handle the EnumerateNamedStreams and CloseNamedStreamsEnumeration events in order for alternate data streams to function correctly. Additionally, the application's GetFileInfo and EnumerateDirectory event handlers must take into account requests made by the OS to work with the alternate data streams.
Note that alternate data streams are an expected feature of the NTFS filesystem; if the application is identifying its virtual filesystem (via FileSystemName) as NTFS, supporting alternate data streams is recommended.
Note: This property cannot be changed when Active is true, and cannot be changed within events.
