TeraCopy's user interface is a pair of efficient dialogs, one an icon-based control panel that you use to add, copy, move, test, and delete files, and a second interface that pops up to do the work. After we installed TeraCopy, it opened with this second interface in minimized mode, a tiny dialog with twin file directory fields--one for source files, the other for the target folder--that double as progress bars for file transfers. Clicking More expands the interface to a multifile view for batch operations and accesses the Clean Up, Verify, and Delete controls as well as a file menu button that includes Options; you can also access this interface from the Start Menu. A drop-down menu lists recent operations with time stamps for quick retrieval. Selecting TeraCopy on a file's properties menu calls up a different, icon-based navigation and control panel. We opened this interface and used the browsing tool to add a file to copy and create a destination folder, and then clicked Copy. The operation was successful but concluded so quickly that we had to open the target folder and check the file's properties to verify that anything happened at all. We also tried the Test feature in this view, which verified an ubuntu ISO disk image in about 2 seconds. You can even associate TeraCopy with .sfv and .md5 files in its options dialog or during installation.
TeraCopy is a nifty piece of freeware that improves the copy/move function in Windows and adds useful extras like checksum calculation and permanent delete. We tried it in both Windows 7 and XP, and recommend it for all Windows users.
