'File Box Extender', and 'Tera Copy'

File Box Extender

FileBox enhances Windows by adding several advanced functions to the standard Open File and Save File dialog boxes. FileBox adds two handy buttons to these standard dialogs, which appear on the right side of the Windows dialog box title bars. These buttons appear next to the minimize, restore, and maximize buttons with which you're probably already familiar. FileBox can also forcibly resize the standard Windows file management dialog boxes so they're bigger, and thus easier to use if you've got lots of files in a folder. FileBox eXtender has a nifty option to display these buttons on Windows Explorer folders too, and this can greatly speed up navigation through today's huge hard disks.

Tera Copy

TeraCopy is a compact program designed to copy and move files at the maximum possible speed. TeraCopy uses dynamically adjusted buffers to reduce seek times while Asynchronous copy speeds up file transfer between two physical hard drives. Pause and resume file transfers at any time to free up system resources and continue with a single click. In case of copy error, TeraCopy will try several times and in the worse case just skips the file, not terminating the entire transfer. Finally, TeraCopy shows failed file transfers and lets you fix the problem and recopy only problem files.
