To be more specific, when you try to copy a 300GB file to a drive with 50GB free space, teracopy v3 does abort, while teracopy v2 in the same situation will warn you that there is not enough free space, but if you decide to continue, then it will copy all the data that it can up to fill the destination drive, and then sets the teracopy window in a blink status "Destination drive is full please free space...", it does not abort the copying and remains waiting, and in the event that the destination drive free some space it resumes the copying automatically, this is a desired behaviour in lots of situations:

-  Copying a windows file with the compressed atribute (300GB that really occupies 20GB) to a drive with 50GB free in a windows folder with the compressed attribute set, this can not be done with windows explorer, neither with teracopy v3, but teracopy v2 did it like a charm.

- Copying a big file in a drive that now does not have the space, but you know that it will have it soon, but you want to start to copy the file now because it has a big size (100's GB), the transfer speed is slow (it will take many hours, because it is a network drive) and you can not wait to free the space before.
