This utility is the opposite number to formchk. It converts a formatted checkpoint file to a binary checkpoint file, in a format appropriate to the local computer system:
$ unfchk Formatted Checkpoint file? water Read formatted file water.fchk Write checkpoint file water.chk
The utility applies the extension .fch to the specified filename on Windows systems and the extensions .fchk on other computer systems.
Note that formatted checkpoint files can be used as a data exchange format between computer platforms. Use formchk on the originating computer and unfchk on the target computer to create a binary checkpoint file.
