TeraCopy is a compact program designed to copy and move files at the
maximum possible speed, providing the a lot of features:
It is a total replaceable program for windows file copy service which is really fast.
For example I can copy a 700MB film in 30 sec from teracopy against about 2 mins in Windoze.
Further it supports pause and resume of copyings.
Here's a description about it in their site. http://www.codesector.com/teracopy.php
Copy files faster. TeraCopy uses
dynamically adjusted buffers to reduce seek times. Asynchronous copy
speeds up file transfer between two physical hard drives.
Pause and resume file transfers. Pause copy process at any time to free up system resources and continue with a single click.
Error recovery.
In case of copy error, TeraCopy will try several times and in the worse
case just skips the file, not terminating the entire transfer.
Interactive file list. TeraCopy shows failed file transfers and lets you fix the problem and recopy only problem files.
Shell integration. TeraCopy can completely replace Explorer copy and move functions, allowing you work with files as usual.
