GioFILE_ATTRIBUTE_ID_FILE

A key in the “id” namespace for getting a file identifier.

Corresponding GFileAttributeType is G_FILE_ATTRIBUTE_TYPE_STRING.

An example use would be during listing files, to avoid recursive directory scanning.

For local files on Linux, this is a combination of the file’s device number and inode, so is invariant with respect to hard linking. The format used by other VFS implementations may vary, and some VFS backends may not set it.

For simply seeing if two GFile instances refer to the same path on disk, see g_file_equal().
