File IDs

File IDs are used by some system components and third-party applications as an alternative to file names. IDs associated with files must be unique within a filesystem and should not change over time.

The root directory (\) always uses the predefined ID 0x7FFFFFFFFFFFFFFF.

For proper File ID support, an application must do all of the following:

If an ID, returned during directory enumeration, is 0, the class will generate an ID. This generated ID is not guaranteed to be unique, especially under heavy load. FileIDs, including the generated ones, are kept in the metadata cache. If the metadata cache is disabled and IDs are not provided by an application, the driver will fail to provide proper File IDs and open files by ID, which can prevent operations of components and applications that rely on File ID support.
