It is very simple to use this tool: In windows explorer, select all the zip files which you want to unzip.(if no .zip files are selected, the files will be ignored), then right click the mouse, the popup menu will give you two choices:( make sure your mouse points to the file, not the folder, otherwise it doesn't work) 1.) Unzip all to ..... 2.) Unzip all to XXXXX (XXXXX means current folder) The 2.) Choice will unzip selected files into current folder. The 1.) Choice will pop up a window and you can select folder or path Note: 1.) This software is still in beta testing. It may have some bugs. Your suggestions are appreciated. 2.) If you can't get the two choices in the popup menu when you right click, then right click ctrxmenu.inf in windows explorer, then select "install". You will get that. 3.) Uninstall: in windows control panel, select add/uninstall software and select Batch Unzip. 4.) If you install Batch Unzip in the WinNT or Windows 2000, you need log on as administrator
