Folder View is a free (freeware) add-on for Windows that drastically enhances the way you browse the folders on your system.

Files are often scattered around many different folders on the harddisk and locations on the network. Every time you want to copy, move, open or save a file, this situation leads you to a quest through levels of folders.

With Folder View, these quests are over. Folder View enhances the Windows file Explorer by making all folders you need available in a single click. It integrates with other applications, speeding up opening and saving of files and also lets you copy and move files very quickly.
