Start copying using TeraCopy!

TeraCopy is a tiny freeware program that is an alternative for the default Windows XP (or Vista) file-copying tool. It copies files at the maximum possible speed, providing the 'current status' of the copying (which includes the estimated time of completion, %left, no. of files completed in batch copying etc..) and it also has an error recoverability feature which is a terribly missed feature in the default copying application.

In case of a file-copy error, it will try several times again to copy the file. And incase a copy still isn't possible it will not terminate the entire copying process (unlike the default copying application in Windows which abruptly stops the copying), but it will just skip the faulty file and copy the rest of the files successfully.
Teracopy also displays the speeds at which files are copied and also offers a unique feature of pausing and resuming a file-copying process.

A portable version of Teracopy is also available incase you're running a slow system.

So, XP and Vista users, stop just copying and start teracopying now!
