  File copying is done a bit at a time, it doesn't copy the whole file in one massive hit. So it reads a bit of the source file into memory, writes it to the destination drive then repeats the process as often as necessary to finish the transfer.
  
  So the only real limit is how much free space there is on the destination drive.

  no limit as such though certain copying methods offer more resilience then file manager.

  when copying a file you'll need to know the size of the file and how much free memory is available so you can pick the correct value on reading into the buffer and writing it out again so to speed up the copying while not impacting on performance too much

  Forty two.
  
  Incidentally I wonder if anyone else knows this thing that I am about to tell you.
  
  Originally my answer was 42,. However when I typed that, a message told me that a posting must be at least 5 characters long. So the blooming rules spoilt my joke.

  forty two is more than 42. That's why i said the answer is six not just 6.

  If I was transferring 1TB of data, how can Teracopy remember so much information.
  
  How exactly does this work?
  
  Thanks

  
  If you were to copy a book by hand you dont need to remember the whole book to do it. You read a bit, write it, read a bit more, write it.
