Hi kicko, I assume you are copying it to a SFS2 or JXFS partition correct? These are the only FS that support files >4GB
If so then have you tried copying it to a memory card then putting the memory card into a 7 in 1 (I have a cheap Dick Smith interface that has always works - I don't know why) transfer device and copying to the Amiga HD once that mounts.
I haven't had any problems copying larger files but I hadn't done alot of this kind of thing in general.
