There is an elegant solution, Win32::ChangeNotify
use Win32;
use Win32::ChangeNotify;
my $appdir = Win32::GetFolderPath(Win32::CSIDL_APPDATA);
my $notify_dir = $appdir . '/Provider/Application/';
my $notify_file = $notify_dir . 'yourfile.txt';
my $notifyObj;
if ( $notifyObj = Win32::ChangeNotify->new( $notify_dir, 0, "LAST_WRIT
+E" ) ) {
print "We have a notifyObj object\n";
$mw->repeat( 2000, \&checkNotify );
}
else {
print "Application not installed on this machine\n";
}
sub checkNotify {
my $rv = $notifyObj->wait(0);
print "Found a change\n" if $rv == 1;
$notifyObj->reset;
if ($rv) {
# DO what you need to do
}
}

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).
