I use them to reduce hassle, such as copying files without having to run Windows Explorer or for setting up a virtual drive... I use the xTree Pro replacement below to search thousands of files (C++ or AS3) for a text string by using a batch file to set up the virtual drive with one command: subst Z: c:\pathToSubDirectory and I then I run ztreewin to log ALL the files on Z with a ".cpp" or ".AS" extention. I just searched 5800 C++ files in 50sec. John www.ztree.com/html/ztreewin.htm http://www.ztree.com/html/ztreewin.htm
