+ * initial scan.  If the application won't use
+ * WIMLIB_WRITE_FLAG_SEND_DONE_WITH_FILE_MESSAGES while writing the WIM archive,
+ * this flag can be used to allow the library to enable optimizations such as
+ * opening files by inode number rather than by path.  Currently this only makes
+ * a difference on Windows.
