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
}
}
