### Copying Display Driver-Related Files

There are several factors that can complicate the copying of display driver -related files from source directories to target directories. First, display driver files might be sufficiently large and numerous to span more than one source diskette. This can easily occur when several display drivers that support different display resolutions are bundled together on the same diskettes (along with their associated font and resource files). Second, to save space within the source directory, it might be desirable to place packed files within the source directory. If so, the packed files should be unpacked when they are copied to the target directory. Third, the display driver packager might wish to specify file version checks that are to take place before file copying is performed. Such checks are valuable because they can prevent the inadvertent replacement of updated display driver files by older versions of the files.
