PKWARE FEATURES
The following features are available with PKWARE Version 1.0
(PKZIP/PKUNZIP/PKSFX) Compression Programs.
Special file handling capabilities will automatically
recurse through subdirectories and store pathnames within
a ZIP file. These paths can then be created on extraction
if they do not already exist.
A file that has been created as a self-extracting file can
be treated as a normal ZIP file. All PKZIP and PKUNZIP
options (except -v View) will be valid.
Files contained in a ZIP file can be viewed in several
different ways. For example, the can be sorted by:
compression ratio, size, date, name, or extension.
Special file attributes (hidden, read-only, system) can be
masked during creation or extraction of a ZIP file. PKZIP
can also be configured to include or not include hidden and
system files.
Individual file comments (up to 60 characters in length)
can be programmed for each file in the ZIP file.
OS2GIF Version 1.0
OS2GIF is a NON PM OS/2 application to display GIF files on EGA or VGA
video systems. The 256 color GIF files will require a VGA adapter for an
enjoyable picture. OS2GIF supports a virtual screen larger than the physical
video screen which allows panning over the image.
Currently OS/2 Presentation Manager Version 1.1 does not effectively
support the 256 color mode of the VGA, this limits PM to a dithered image
display. Since many GIF files are in 256 colors, the loss of the full beauty
of the colors is significant. However
OS2GIF performs direct I/O to the video adapter with OS/2 Ring 2 I/O code,
providing full functionality of the video systems under OS/2.
Also, currently OS/2 PM has performance disadvantages for image display.
It is expected that these shortcomings may be addressed in future versions of
OS/2, but until they are OS2GIF will not use PM.
