First, a couple of questions:
- How accurate do you need to be? (this method can give a slightly different number for free space than right-clicking and selecting properties)
- Can you map a drive to the share before checking, and disconnect after?
- Is Windows Script Host installed?
If the answer to these questions are "99% is good enough","yes" and "yes", try this: #!perl
use warnings;
use strict;
use Win32::OLE;
my $fs = Win32::OLE->CreateObject('Scripting.FileSystemObject');
my $d = $fs->GetDrive('g:');
print $d->{TotalSize}, " total\n";
print $d->{FreeSpace}, " free\n";
print $d->{AvailableSpace}, " available\n";
print $d->{TotalSize} - $d->{FreeSpace}, " used\n";
__END__
Output on my system, with G: mapped to a Samba share:
19447939072 total
16677601280 free
16677601280 available
2770337792 used
where AvailableSpace is the space available to you and FreeSpace is total free space. Note - this code requires you already have the drive mapped before you try it. Update: added closing </ul> tag
Update 2: Please read BrowserUK's caveat below!

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).
