<?php
// This is an application for maintaining the file system of a web server.
// It will display the file system from it's resident folder and down.
// It will not move up in the folder tree from it's resident folder.
//  (That is so a user can have his own folder and won't access others.)
//
// It's features are:
//  list folders (The folders are listed in the first column)
//  list files (The files are listed in the next three columns: images, scripts and .txt files)
//   (the images listed can either be a list of filenames, or displayed as thumbnails)
//   (click on the image name or thumbnail to show the full size image)
//  edit a file's contents and save it with the same name or different file name,
//   in same folder or another one
//  display listing of a file
//  delete a file
//  delete an empty folder
//  while editing a file, find a text string
//  navigate back up the tree using unique navigation links
//  create a new file and then enter text into it
//  create a new folder
//  upload a file into the currently displayed folder
//  download a file to your computer
//
// This application uses the php class of Olaf Lederer, Easy PHP Upload class, which can be found here:
//   http://www.phpclasses.org/browse/package/1841.html
// The upload_class.php file is really all you need for this application
//
// This application uses the php class of Slava Ivanov, Downloadfileclass, which can be found here:
//   http://www.phpclasses.org/browse/package/699.html
// The downloadfileclass.inc file is really all you need for this application



// Version 1.0.1   27Feb2006
// Corrected a number of errors in the code. Too many to list.
//
// Version 1.0.2   28Feb2006
// corrected a couple of other errors that were missed.
//
// Version 1.0.3   04Oct2006
// Added a download feature for each file or image to the class.
//   Version 1.0.2 should still work with the updated class.
//   Changes to this application were comments.
