File transfer interruption

Hi,
I started to transfer a file from a server to my computer but I interrupted the transfer since the time needed for the transfer is long. I am wondering wheather this interruption of transfer could modify the original file (located in the server).
Best regards,
Redha

Generally, no. Of course, a server is free to do whatever it likes with the file. But I've never seen a server to modify a file, when a download is interrupted.
