Jean,
OK now I see where the conversation is taking place. I don't usually get emails for UT questions.
As I said, file sizes are limited to 2gb in VFP (that is all files of any type). When any file is greater than 2GB VFP will NOT open the file at all. I have never seen error 1150 related to file size. Error 1150 is regarding meory (RAM) available to VFP for processing a request. Something is limiting the amount of memory available and VFP cannot finish the request it is processing.
