What is an HCW file

HCW files mostly belong to HTML Help Workshop by Microsoft Corporation. The wizard macro is an undocumented HTML Help conversion tool for converting .HPJ to .HHP format. To use the technique create a CONVERT.HCW file using any text editor (the name can be any rootname with the .HCW extension). The file should contain a minimum of two lines. The first of them is the full path to the .HPJ file and the second is the full path to the .HHP file you wish to create. Note: these are full pathnames including the drive and all subdirectories on each line. Once created, open the file in HTML Help Worskhop. There should be a quick flash of a dialog box and afterward you should find the help file fully converted. If you need to convert more than one help file add additional line pairs and all will be converted when you run the file in HTML Help Workshop.
