### Copying Display Driver-Related Files

Several factors can complicate the copying of display driver-related files from source directories to target directories. Display-driver files might be sufficiently large and numerous to fill more than one source diskette. This can easily occur when several display drivers, supporting different display resolutions, are bundled together on the same diskettes (along with their associated font and resource files).

To save space in the source directory, it might be desirable to use packed files. If so, however, the packed files must be unpacked when they are copied to the target directory. The display driver packager can specify file version checks to be made before the files are copied, because the checks can prevent the inadvertent replacement of updated display-driver files by older versions.
