FEATURES
The PKZIP 2 software utilities include many features. Here are just a few
of them:
Improved Compression. PKZIP 2 implements a new compression algorithm
called Deflating. Deflating has varying levels of compression and speed
available, allowing you to specify the method of compression to be
employed. Both the speed and amount of compression are improved over
previous versions of PKZIP.
Multi-volume archive support. PKZIP 2 can create .ZIP files larger than a
single floppy disk.
Subdirectory storage. PKZIP 2 can find and store subdirectory pathnames
within a .ZIP file. Files can then be restored to their original
subdirectories, or they may be re-created. Storage includes empty
subdirectories.
Automatic detection and utilization of 80386 and 80486 CPU's, EMS and XMS
memory, Novell Netware, and 32-bit DPMI. PKZIP 2 gets the most out of
your machine by using the power of modern CPU's. EMS and XMS support
offer the ability to process more files with less available conventional
memory. Novell Netware and 32-bit DPMI support offer speed improvements.
The above features also allow you to get the best performance when in a
DOS session under OS/2 or Windows. OS/2 and Windows offer EMS, XMS and
32-bit DPMI without your using extra drivers.
Memory Requirements. PKZIP requires a minimum of 183K of conventional
memory. If EMS is available, the conventional memory requirement is 85K.
PKUNZIP requires 90K of conventional memory. PKSFX requires a minumum of
71K of memory.
Easy to use configuration program. PKZIP 2 can be configured to best suit
your needs through the use of the PKCFG program.
PKSFX Junior and PKUNZIP Junior. These "Junior" programs use very little
memory and are extremely small. Although they are reduced in ability,
their small size makes them very useful.
Password Encryption. Sensitive data files can be scrambled with password
protection. The security of this feature has been improved in PKZIP 2.
Authenticity Verification. Users requiring authentication of archive
files may request an Authenticity Verification code. This allows users to
create .ZIP files which reveal tampering.
