Explorer Assistant XP is a great enhancement for the regular Windows Explorer and Internet Explorer! It allows you to run only one instance of Windows explorer and see files in different folders at the same time. It enables you to easy manage files: copy and move, open and delete files, just as usual. Explorer Assistant supports the typical drag & drop handling of files. It is fully interoperable with "standard" Explorer or the desktop. You can set many fovorites with different folders and moving from one folder to another by clicking on a one button! You've decided to perform some spring cleaning on your hard drive? It won't be too long until you begin spawning several windows, creating a confusing desktop mosaic that's enough to make you turn off your PC and go to sleep. Forgot about it! Organize your downloads and files better with this window and file manager - Explorer Assistant XP!
