I found these programs on the interwebs last week and thought they might be useful; the first, TeraCopy, significantly sped up my file transfer speed in Windows Vista and seems a lot more intelligent than the built-in Windows Explorer copy/move dialog. The other nice thing about TeraCopy is that it seamlessly replaces the original Explorer dialog, so all you have to do to use it is just drag and drop (or Cut/Copy and Paste with the menu or keyboard shortcuts) like you usually would.
The second, Direct Folders, improves the File Open/Save dialog and adds a shortcut menu to any folder in Explorer.
- TeraCopy (http://www.codesector.com/teracopy.php)
Copies files faster and smarter than Windows Explorer’s built-in copy function (this program replaces it) – asks you questions at the *beginning* of the copy operation instead of getting halfway through, then asking if you want to overwrite something. - Direct Folders (http://www.codesector.com/directfolders.php)
Makes it easier to navigate to a specified set of folders – gives you a shortcut list by double-clicking on the desktop, or the blank space in any Explorer folder window.
