NZIP AND WHZIP FEATURES
The following features are available in Version 0.98 of Nzip
and Whzip.
Whzip
-----
1) With no file name search string found on command-line,
Whzip lists all PKzip files with file extension "zip"
(e.g., *.zip) in all subdirectories in current disk
drive.
2) With file name search string found on command-line,
Whzip finds files matching search string for all PKzip
archive files (*.zip) in all subdirectories in current
disk drive.
3) Whzip lists all pertinent archive information about
each matched file and prompts user if number of files
found exceeds one screen.
Nzip
----
1) Nzip lists all Pkzip files (*.zip) in current directory
2) User may select a zip file to view
3) Most pertinent information contained about the PKzip'ed
files is displayed.
4) User may select to view the contents of any file. Up
to 1000 lines may be reviewed.
5) User may individually select or tag a set of files for
extraction to any subdirectory or disk drive.
Future versions of Nzip will include the extraction of files
to a printer or deletion of files from the PKzip archive
file.
INTRODUCTION
Nzip and Whzip utilities are designed to work together to:
- find archived files in the current directory;
- determine the file to be extracted (view); and
- extract the chosen file to any directory or drive.
Both Whzip and Nzip are designed to be used in any directory
by placing these files in a directory found in the DOS PATH.
REQUIREMENTS AND INSTALLATION
The latest version of PKunzip, Nzip and Whzip files must be
in a directory found in the DOS system PATH. Nzip uses
PKunzip to extract files from PKzip'ed files.
Nzip and Whzip may be installed by copying Nzip.exe and
Whzip.exe found in the distribution floppy diskette to a
directory found in the DOS PATH. To achieve maximum
performance the directory should be on the hard disk and not
run from a floppy diskette.
WHZIP
Whzip is a "whereis" type utility which searches all
subdirectories in the current disk drive for the file name
found in the command-line.
c:> whzip *.pas
Whzip, in this example, will list all PKzip archived files
with a file extension of "pas" to the screen. If the screen
becomes full, the user is prompted and Whzip waits until the
user has presses any key except the ESC key. The ESC key is
reserved to immediately abort whzip and return to the current
directory.
Whzip may also be used to list all Pkzip files to the screen.
This is similar to other whereis utilities.
c:> whzip
Whzip, in this example, will list all PKzip files contained
in the current disk drive to the screen.
NZIP
Nzip is a PKzip archive file viewer and extractor. Upon
execution (no command-line arguments required), Nzip finds
all PKzip files with the file extension of zip (e.g., *.zip)
in the current directory. All PKzip'ed files are displayed
for user selection. If more than 15 PKzip'ed files, the user
may scroll through the list until the desired PKzip file is
found. The user may then press the carriage return [CR] to
select the PKzip file.
The next screen displays most pertinent information about the
archived files in the center of the screen called the list
window. This includes:
1) Name of file
2) Original size of file
3) PKzip method of compression
4) Percent compressed
5) Current compressed size
6) File modification date
7) File modification time
The current version of Nzip, the current directory and PKzip
file is displayed above the list window. The total number of
files and total and original file size are displayed below
the list window. At the bottom of the screen user
information which aids the extraction, viewing, listing of
PKzip files and Quit are displayed.
Use the left and right arrow keys or use the first letter of
the name to select the desired function. For example, if you
want to Extract a file, press the letter "e". The up and
down arrow keys are used to move the listing of the archived
files up and down in the list window.
Files may either be individually selected or a set of files
may be selected by using the space-bar followed by a [CR]. A
small diamond shaped icon on the left side of the file name
should let the user know that the file has been selected.
The [CR] moves the cursor down to the next file. The space
bar also used to deselect files.
Use the normal PageUp and PageDown keys to move one screen
number of files. Use the HOME key to move to the first in
the archive. Use END key to move to the last file in the
archive. The order of the files in the list window are the
same as they were archived.
Because Nzip uses PKunzip to both extract and view a file,
PKunzip must be in the DOS PATH. To view a file, Nzip
creates a subdirectory called "$$$3", extracts the contents
of the file to that subdirectory and then reads the file.
Currently 1000 lines of text may be reviewed with Nzip. This
may be increased in later versions of Nzip. Upon review of
the file, Nzip deletes the file and temporarily created
subdirectory. While viewing a file, all cursor functions are
the same as mentioned before.
The function labeled Zip files allows the user to return back
to the current listing of PKzip files to review additional
PKzip files.
The user may exit Nzip by either depressing the ESC key, the
"q" key (Quit) or moving the left or right arrow key until
Quit is highlighted.
