Re: [Dev-C++] File Handling

[Per W. <pw...@ia...>]

No need to copy one bit at the time. You wan't to copy as large blocks as
possible to keep code efficient. Create a reasonably large buffer - a
reasonably large number n * 4096 should be good - and then read/write
until done. Just notice that the last read/write block might be smaller.
