MetadataCacheEnabled Property

Whether the metadata cache should be used.


bool GetMetadataCacheEnabled();
int SetMetadataCacheEnabled(bool bMetadataCacheEnabled);

Default Value



This property controls whether the file metadata cache is enabled for a virtual drive. The size of the file metadata cache can be controlled using the MetadataCacheSize property.

When enabled, the class caches file information obtained via EnumerateDirectory and GetFileInfo events and uses the cached metadata to serve operating system requests, thus reducing how often the GetFileInfo events fire.

While a file or directory is open, its metadata is kept available in a special record called a File Control Block, regardless of whether the metadata cache is enabled.

For closed files and directories, the metadata is kept in the cache for the time, defined by the UnusedMetadataLifetime configuration setting.

Please refer to the Caching topic for more information.

Note: This property cannot be changed within events.

This property is not available at design time.
