We used to process files at boston childrens hospital with fpd 2.6 that were so large that they would take 6 or more hours per day to run. Never had a problem with size.
We were doing a conversion from a dec??? to a ibm mainframe where they would download the files to us, we would validate them using foxpro, and if we gave the approval, they would transfer the file from the dec to the ibm. Don't quote me on the systems as that was back in the late 80's, early 90's from what I remember, and I've had a lot of beer and stress since then -----Original Message----- From: ProFox [mailto:profox-boun...@leafe.com] On Behalf Of MB Software Solutions General Account Sent: Friday, November 08, 2013 3:25 PM To: ProFox Email List Subject: Re: Working with text files larger than 2GB (VFP9SP2) On Thu, November 7, 2013 1:18 pm, Gene Wirchenko wrote: > Is the entire file required in memory?

I'm just taking 1 line at a time, and writing the string out to a different file based on the first 6 characters of the row. (That's the provider number.) I plan to create this "splitter" program to pare down the behemouth files into smaller ones they can process by provider. (All provider data is separate...no one mixed.) So given that...I don't have to worry how big their source file is then, eh?
