Int 21H Function 0DH
   Summary  Notes  Back
──────────────────────────────────────────────────────────────────────────────
 
▀ This function does not update the disk directory for any files that are
  still open. If your program fails to properly close all files before
  the disk is removed, and files have changed size, the data forced out
  to the disk by this function may still be inaccessible because the
  directory entries will not be correct.
 
▀ [3.3+] Int 21H Function 68H (Commit File) should be used in preference
  to this function because it also updates the disk directory and file
  allocation table.
