Is there a file size limit when sharing files? I was trying to use File Sharing to transfer a rather large file (6 GB) from my Mac mini to my MacBook Pro over WiFi, but the file would get constantly stuck at 6 MB and stop transferring.

Is there a file size limit when using File Sharing?
I don't think this problem is caused by the size of the file, but just one of those random hiccups that happens with AFP sometimes =/

Try using AirDrop if your on 10.7 Lion or higher. Even if your mac doesn't support AirDrop, there is a hidden command to allow for AirDrop to work over the local network (Ethernet or WiFi). See the link below.
