This is a simple, totally free single-file script
that, when placed in a directory and viewed from a browser will list
all the files in that directory and link to them.
The need for such a script is due to the fact many
web hosts turn off directory browsing on the servers, and for good
reason, as it does introduce a certain security risk.
With this simple package, which consists only of a
single file named "index.php", you can drop that one file in any
directory and list all the files in it just like server directory
browsing, and without the risks.
