- ZFV-ZIP Format View, Version 1.11 08-Aug-92
-
-
- Allows you to see how a ZIP file is laid out on disk. Uses windowing to
- step down to lower levels of detail. Displays header offsets and most field
- values, including their interpretation. Admittedly, this program isn't for
- everyone. For the curious and those with a need to know, however, this
- program displays technical data on ZIP files that I haven't seen in any
- other program. New: Switch to set level of filtering for ZIP files.
- Configuration file for default switches. Updated for the Super-fast Deflate
- compression algorithm.

- Purpose:
- ========
- I developed Zip Format View for my own use, but make it available to anyone
- else who might be interested.
-
- ZFV is a free program.
-
- Display:
- ========
- The program attempts to sense the type of display used and adjust color
- appropriately. However, if the user has a color graphics card, but no color
- monitor, the display may be improved by using the DOS command "MODE BW80".
- Conversely, if you do have a color monitor, but the program displays in
- "black and white", try using "MODE CO80".
-
- Alternatively, two switches are available from the command line to force
- black-and-white and color modes. See "Switches" below.
-
- EGA/43- and VGA/50-line modes are supported. At program startup, an attempt
- is made to detect the actual number of lines on the screen, up to a maximum
- of 50, and to adjust the display accordingly.
-
- Syntax:
- =======
-
- Usage: ZFV [switches] [filespec]
-
- If no extension is specified for "filespec", ".ZIP" is assumed. If a valid
- filename is specified unambiguously, the .ZIP file is immediately displayed.
- Either specifying "filespec" using wildcards, or specifying a drive or
- directory name causes a scrollable directory window to pop up. Simply
- typing the program name is the same as specifying "*.ZIP".
-
- Examples: ZFV c: <- current directory of drive C:
- ZFV d:\ <- root of drive D:
- ZFV \download <- download subdirectory off root
-
- Switches:
- =========
- /BW Black-and-White mode. Provided as an alternative to using DOS's
- "MODE BW80" command.
-
- /Fx Where 'x' represents 0/1/2/3, as follows:
-
- F0 - don't filter (fastest)
- F1 - check only for files with the .ZIP extension (default)
- F2 - same as F1, but do a thorough check of .EXE files
- F3 - check all files for valid ZIP files (slowest)
-
- Either '/' or '-' may be used to specify switches.
-
- Entering an invalid switch causes the program to display a brief help screen
- then exit.
-
- Examples: ZFV /h
- ZFV -?
-
- Configuration:
- ==============
- An optional configuration file containing user-selected default switches may
- be created or edited with any editor or word processor which can save pure
- ASCII text files. This file should be named "ZFV.CFG" and placed in the
- same directory from which ZFV.EXE is loaded (DOS 3.0 and above).
-
- Switches, including switch options, may either be separated by spaces or
- placed on separate lines.
-
- Incompatible switches used on the command line will override switches
- included in ZFV.CFG. Switches are evaluated from left to right on the
- command line.
-
- A sample ZFV.CFG file is included in the distribution archive for ZFV.
- After extracting the contents of the distribution archive, ZFV.CFG may be
- deleted if ZFV's defaults are satisfactory.
