Thanks for the clarification. >From what i have understood I think the OP should certainly at least, whatever the files they want to include exactly look like and whichever byte they choose as delimiter, scan the file first for such a byte and if it is actually found replace it with either an empty string or (probably better) some sort of "tag" before applying the contents to the new database. This way they could at least be sure that their chosen delimiter does not split one record into halves. I don't think it makes really any difference which of the bytes that aren't supposed to be present in "text" files is used, one can never be 100% sure that these bytes don't show up nonetheless. I have no idea what these "text files" look like of course. It just seemed -to me - that the fact that the null byte cannot ever be part of a file name might make it slightly more appropriate for this purpose than other candidate bytes. Of course, it depends... Best regards Michael .-.. .. ...- . .-.. --- -. --. .- -. -.. .--. .-. --- ... .--. . .-.
