What is a gcd file and what data are you trying to extract from it?
As bulk88 points out the file that you are trying to parse is an OLE compound document (of which Word documents are an example but your file isn't a Word document).
The smplls utility that comes with OLE::Storage_Lite shows the following in the file format:
$ perl sample/smplls.pl ../LaborHoppe_P1_UNK-0010_09.09.2011_1.gcd
00 1 'Root Entry' (pps 0) ROOT 20.09.2011

01 1 'Audit Trail' (pps 1) DIR 09.09.2011
+17:22:14
02 1 'Audit Trail Property' (pps af) FILE 50
+bytes
03 2 'File Comment' (pps 18) FILE 1

At first glance this doesn't seem to match the unpack statement in your program. Are you sure it is meant to parse the same file format?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
