Brian, I have managed to transfer files over 16MB, but the problem is write/binary %bigfile read/binary ftp://a.b.c/bigfile will read the file into memory before writing. It may be possible to use read/part and write/append to move the file in smaller chunks like bo's movefile.r on www.rebol.org. I would be interested to know if this approach works. btw I have been using 2.1.90.3.1 (ie win32) as 2.2.0.x seem to have problems with ftp to some servers, in my case aix (rebol bug ticket #1256) good luck, john
