Checks the file integrity of a Labbook.
Optional. An integer, delete orphaned files:
Nothing. Renames unreferenced Labbook files with the extension .ORF, and optionally deletes them.
Examines each Worksheet, Dataset and Channel file in the current Labbook and automatically deletes any unreferenced files.
CHKFILES checks if any Labbook files are no longer referenced by Labbook objects. For example, temporary files will not be deleted if the machine improperly shuts down while a Labbook is open. These temporary files will be unreferenced in the next DADiSP session and CHKFILES can be used to automatically remove and recover the file space.
