The difference is probably that IE initially creates the file with full 
size and then overwrites it. This is at least the case if you copy files 
with explorer, copy, xcopy or CopyFileEx().

FireFox, Cygwin's cp and most other programs use regular sequential 
write. This may lead to fragmentation when the disk has less space.
