-
- 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.
-
-
