Hello, I've written a simple script which can recurse into subdirectories when needed, and print out an HTML table with with details about the files it finds.  The problem is that after I run this script, if I try and rename one of the folders it has recursed into, I get an error message which reads:

"Cannot rename [folder name]:  There has been a sharing violation.  The source or destination file may be in use."

Note that I can still rename files, just not folders.  If I stop and start IIS, I am able to rename folders until I run the script again.  I believe I'm using the closedir() function correctly, and have even echoed out when the directories are opened and closed to make sure I'm not messing up.  One last thing to note is that this script is being run on an NTFS partition.  A copy of the script follows:


<?php

// $hddir is the hard drive directory passed into this function from the calling page
// $mode can be either "single" or "recurse"
// $order is just ignored right now, but I would like it to be "alphabetical", "size", etc.


function list_dir($hddir, $mode, $order) {
	$webdir = "http://www.foo.com" . str_replace("/inetpub/www_root", "", $hddir);
	$handle = opendir($hddir);
	chdir($hddir);


	// if there are files in the directory, print out the table header and set the flag
	// once we find a file, don't run the test (and print out the table header) again
	while (($file = readdir($handle)) && ($file_count < 1)) {
		if ($file == '.' || $file== '..') 
			continue;
		else if (is_file($file)) {
			echo "<table border=\"0\" cellpadding=\"2\" cellspacing=\"2\">";
			echo "<tr><th></th><th class=\"high\">Filename</th>";
			echo "<th class=\"high\">Size</th>";
			echo "<th class=\"high\">Modified</th></tr>";
			$file_count += 1;
		}
	}


	rewinddir ($handle);					// start reading again from the beginning of the directory
	while ($file = readdir($handle)) {		// while we can read an entry from the directory (files and dirs)
		if ($file == '.' || $file== '..') 
			continue;

		else if (($mode == "recurse") && (is_dir($file)) && (substr("$file", 0, 1) != "_")) {	// don't recurse directories which begin with an underscore
			$dir_count += 1;
			$places_to_go[$dir_count] = "$file";
		}

		else if (is_file($file)) {
			$extension = ''; 
			$parts = split('\.', $file); 
			if (count($parts) > 1) $extension = end($parts); 
			if (!$extension && count($parts) > 2) $extension = prev($parts);
			
			if (($extension == "doc") || ($extension == "DOC") || ($extension == "rtf"))
				echo "<tr><td><img src=\"/pics/icons/word_sm.gif\" width=\"20\" height=\"19\"></td>";
			else
				echo "<tr><td><img src=\"/pics/spacer.gif\" width=\"20\" height=\"19\"></td>";
			
			echo "<td bgcolor=\"silver\"><a href=\"" . $webdir . "/" . $file . "\" target=\"_blank\">" . $file . "</a></td>"; 
			
			$j = 0; 
			$ext = array(" Bytes", " KB", " MB", " GB", " TB"); 
			$file_size = filesize($file); 
			while ($file_size >= pow(1024,$j)) ++$j; 
				$file_size = round($file_size / pow(1024,$j-1) * 100) / 100 . $ext[$j-1];
			echo "<td bgcolor=\"silver\">" . $file_size .  "</td>";
			
			$filemod = filemtime($file); 
			$file_modtime = date("F j Y h:i:s A", $filemod); 
			echo "<td bgcolor=\"silver\">" . $file_modtime .  "</td></tr>";
		}
	
	}	// end while we're reading files from the directory


	// if we printed out a table, header (and contents) we should cap it off
	if ($file_count >= 1)
		echo "</table>";


	// if there are other directories to recurse into that were stored in our array, 
	// print out the name of the directory, and call this function with the new directory name.
	if ($dir_count >= 1) {
		for ($x=1; $x<=$dir_count; $x++) {
			echo "<h4>$places_to_go[$x]</h4>";
			echo "<dir>";
			$newdir = "$hddir" . "/$places_to_go[$x]";
			list_dir($newdir, "recurse", "alpha");
			echo "</dir>";
		}
	}


	chdir ("..");
	closedir($handle);
