### Subdirectory Structure

The subdirectory structure on the startup driver created by the hardcopy driver installation is as follows:

             OS2\DLL\VENDORNAME\CLASSNAME\DRVNAME

An example of this subdirectory structure might be OS2\DLL\HP\PCL\LASERJET. Most hardcopy drivers need to be installed only in one subdirectory. In this case, omit CLASSNAME and ensure that VENDORNAME is equal to the name of the DRV file.

For example, to install a Postscript** driver in a subdirectory, you might use the following extended attributes:

             VENDORNAME = PSCRIPT
             REQUIREDDRIVERFILES = PSCRIPT.DRV
             OPTIONALDRIVERFILES = PSCRIPT.HLP

This will install the PostScript driver into a subdirectory named PSCRIPT.
