For example, say the user is browsing directory C:\users\tom\images\vacation and you want to lock everything to the \users directory. Have the script expect http://localhost/script.php?path=users\tom\images\vacation instead of the full path. You can then do some basic string parsing to determine the first folder (in this case "users") and ensure that that matches a defined set of acceptable folders. So if($first_dir != "users"){ echo "this is an invalid directory"; } Etc. Also, if someone tries to pass "C:\" into $path, it'd end up getting parsed as "C:\C:\", which will obviously be an invalid directory. This would allow the user from doing something like http://localhost/script.php?path=windows\system32 since "windows" isn't in the approved folders list. I'm sure there's a bunch of other ways of doing this, but it's the first that popped into my head. -M
