This function takes a directory, and a "folder" search parameter.
If it finds the directory (either in single level, or any sub folder) it will return the relative path of that folder. "FALSE" if not found. Skips over files and "." and ".." directories. Recursive by default.

Takes a given directory and lists all the files and folders under it, including sub folders. Resulting array contains associative (folders) and indexed (files) elements. Doesn't return "." and ".."

Customizable recursive directory scanner.

Recursively delete a directory, emptying all contents.

Copy a file to a new location, optionally marking the file as a temporary file (to be deleted on application exit).

Note there are issues for temporary files - not all the parent directories that might be created are guaranteed to be deleted - only the immediate parent directory will be deleted on exit if created. Other higher-level directories will not be deleted, even if the file is marked as temporary.
