It's late, and you need to copy a bunch of files from one folder to another, one drive to another. Whatever the case, you select your folder, copy it (Ctrl-C is my favorite), then navigate to the destination and paste (Ctrl-V, here).
Then begins the waiting game.
|Windows Explorer, in all its minimal uselessness|
If you're copying thousands of files in thousands of folders, and the process stops somewhere along the way, you're stuck digging through all those files, all those nested folders, trying to find out where to resume.
TeraCopy is without a doubt one of the best utilities I have ever used. It easily enables you to copy a large number of files and folders with the ability to verify whether the copy process completed successfully or not for each and every item in the list. Furthermore, it lets you retry any failed items individually or en masse.
|TeraCopy can optionally show you the entire list of files as they're being copied.|
Another feature I enjoy is that TeraCopy dynamically adjusts buffers while copying to speed up the copy process, making Windows Explorer crude in comparison. It even provides you with a live view of the data transfer speed in the title bar!
The thing I like most about TeraCopy, though, is that once installed it can completely replace Windows Explorer for all your file and folder copying needs. Given that I can copy and paste a huge number of files, and then be met, say, the next morning with a detailed report showing me details about any items that failed to copy, it really does help me sleep easier.
