PHP File Manager
PHP File Manager is based on PHPFM 0.2.3 by Morten Bojsen-Hansen.
Note: There are some problems with the file editor that could lead to corruption of the file being edited. If you want to use it for file editing (not recommended), check that the editor can correctly interpret the character set you are using by trying it on a test file first.
