Once you have made a backup of your Joomla site, you may want to print the entire directory structure or a list of files. If you use Windows, you seem to be out of luck since explorer does not have a print option. Well, there is hope with Karen's Directory Printer, a free opensource program that allows you to print directories and lists of files.
Karen's Directory Printer prints the name of every file on a drive, the file's size, date and time of last modification, and attributes (Read-Only, Hidden, System and Archive)! The list of files can be sorted by name, size, date created, date last modified, or date of last access. A real handy utility for Windows users.
You can download Karen's Directory Printer here along with other useful tools (Windows users only).
