This can be achieved by using the <code>setFileSize</code> function in [http://hackage.haskell.org/packages/archive/unix-compat/0.1.2.1/doc/html/System-PosixCompat-Files.html#13 System.PosixCompat.Files]: |

<lang Haskell>setFileSize :: FilePath -> FileOffset -> IO () |
|||
-- Truncates the file down to the specified length. |
|||
-- If the file was larger than the given length |
|||
-- before this operation was performed the extra is lost. |
|||
-- Note: calls truncate. |
