NAME

6       zipdetails - display the internal structure of zip files
7

SYNOPSIS

9           zipdetails [-v] zipfile.zip
10               zipdetails -h
11

DESCRIPTION

13       Zipdetails displays information about the internal record structure of
14       the zip file. It is not concerned with displaying any details of the
15       compressed data stored in the zip file.
16
17       The program assumes prior understanding of the internal structure of a
18       Zip file. You should have a copy of the Zip APPNOTE file at hand to
19       help understand the output from this program ("SEE ALSO" for details).
20
21   OPTIONS
22       -v   Enable Verbose mode
23
24       -h   Display help
25
26       By default zipdetails will output the details of the zip file in three
27       columns.
28
29       Column 1
30            This contains the offset from the start of the file in hex.
31
32       Column 2
33            This contains a textual description of the field.
34
35       Column 3
36            If the field contains a numeric value it will be displayed in hex.
37            Zip stored most numbers in little-endian format - the value
38            displayed will have the little-endian encoding removed.
39
40            Next, is an optional description of what the value means.
41
42       If the "-v" option is present, column 1 is expanded to include
43
44       ·    The offset from the start of the file in hex.
45
46       ·    The length of the filed in hex.
47
48       ·    A hex dump of the bytes in field in the order they are stored in
49            the zip file.

TODO

52       Error handling is still a work in progress.  If the program encounters
53       a problem reading a zip file it is likely to terminate with an
54       unhelpful error message.
