TREE: The TREE command graphically displays the subfolders contained in the folder you point it to, using a tree structure to show the hierarchy. The '/f' switch for the TREE command will also display all the files in each folder. You can send the output of the tree command to a text file by typing: 'tree (your drive and directory) > mytreefile.txt' and open it in word (with DOS formatting) for a nice printable directory list.

NETSTAT:The NETSTAT command can be used to display a wealth of networking and port information that would otherwise not be available through the Windows interface without the use of third-party software. Its most vital function is the ability to show what ports are communicating data or open and listening for data at any given time.

When used by itself, 'netstat' will display currently active network connections between your system and any other systems on your network or the Internet. The '/a' switch shows all current connections along with all open and listening ports.

The '/o' switch shows the process ID which belongs to each connection. This can be handy for tracking and identifying unwanted software such as spyware on your system. Use the TASKLIST command to match this process ID to the processes currently running on your system.
