ASCII data import problem.

When I import ASCII data, I get error as
"Adding records would overflow file"
How to over come the error?

If Intraday, MS has limitation on number of records it can store (Dont remember exact figure, but its around 60,000 Quotes per ticker)

how to change it?

Don't think you can change (that's why its called Limitation ). Max you can do is delete earlier quotes or better still, migrate to AB

Are you trying to paste the data directly into the downloader table? If so, then this problem may come.

Otherwise, split the data into two files, import them separately in different MS name. Once done, merge the two MS files using downloader.
