File System Function Library
Working with files & the FileSystem object is actually fairly easy. James Lind?n presents a full

featured function library to make it even easier.

Click Here to download the function library include file.

The purpose of this script is to make working with the file system easier. It includes functions

for manipulating directories and files. Whether you want to use this script for a web based file

manager, or simply want to make working with text files easier, the script has functions which

will streamline your code.

To use these functions, save the file above (or copy the code here to an include file), upload

the include file to your server, and include it in your scripts like this:

<!--#include file="filesys.txt"-->
