I suspect somehow this file was not properly terminated (eg ctl-z).
it is 5.5 GB and I'm trying to load it into Access. It responds too quickly to have tried to read the file and found out it was too big. I am thinking someway to copy binary and add a ^Z file? It's been 2 decades since i did something like this and I suspect whatever worked then won't work with 5.5 GB - = - Vasos Panagiotopoulos, Columbia'81+, Reagan, Mozart, Pindus, BioStrategist http://www.panix.com/~vjp2/vasos.htm ---{Nothing herein constitutes advice.

*+-I seriously doubt you were working with 5.5GB files 20 years ago
Isn't it obvious from the way I said it? Not really. If its a file from 20 years back (one possible way to read your statement) I also doubt it. 20 years back (1994, a pre Windows time) even big *drives* where measured in MB, not GB. And you would have had a quite special program to work with filesizes at least three times the processors address-bus width. Heck, even recently (on Fat32) filesizes where limited to 2 GB. Taking the other way to read it and assume you just now created/got a datafile of 5.5 GB you can't read, what makes you think its the ctrl-Z thats doing it ? It might very well be the (old) program itself not being able to coope with a file over 2 GB in size ... I am thinking someway to copy binary and add a ^Z file? Type "copy /?" for full info. Create a file with a ctrl-Z (type ALT 26 if I'm not mistaken) in it and use the "/b" option to "+" the files together (to a new one) : copy /b Srcfile1 /b Srcfile2 Trgfile Hope that helps.

No, my line was bad and I was unable to finish.
(It was wierd. It wasn't just noise but I was typing one thing and getting something else. Hadn't seen THAT in decades since I was dialing up with my hp2621a terminal alone) My goal is to add an EOF (ctl-Z) to the end of a 5.6GB file out of hopes of fixing it. THe file came as a zip file on a CD from the provider. THey warn of problems but the first time it was they who sent a truncated file. It is possible I could fix it by using a different unzipper, or read it into openoffice base. Or I can break the file up. I'm thinking something like copy -b x.csv+ctlz.cod y.csv where ctlz.cod just had ctl-z (EOF) But I don't know how this would behave with 5.6GB - = - Vasos Panagiotopoulos, Columbia'81+, Reagan, Mozart, Pindus, BioStrategist http://www.panix.com/~vjp2/vasos.htm ---{Nothing herein constitutes advice.

Vip2,
THey warn of problems but the first time it was they who sent a truncated file. And pray tell, how do you know that they did send a faulty, truncated file ? Because of the problem ? That might well be caused by something else ... In other words: Do not assume a ctrl-Z at the end will solve everything. Also, most modern programs (DOS v3.3 or later) have no problem with a textfile just ending, without such a ctrl-Z. But I don't know how this would behave with 5.6GB There is only one way to know: try it ! Suggestion: first backup the origional (if you did not save the ZIP-file it came from), so you can restore it when something goes wrong. I'm thinking something like copy -b x.csv+ctlz.cod y.csv where ctlz.cod just had ctl-z (EOF) Yeah, that is what I suggested too. As you are responding as if you have not read it I have no idea if you will actually read this either. :-\ Regards, Rudy Wieser schreef in berichtnieuws ...

vjp2,
Someone in the NT batch newsgroup suggestes: copy x.csv+nul /a for which I am most gratefule Nice, appending an "empty file" and depending on the "/a" switch to have the copy command append a ctrl-z. One drawback though : If, for whatever reason whatsoever, the CSV contains a ctrl-z somewhere in the middle you will throw the remainder of the file away. In other words: check the size of the result. If it apears to be shorter than the origional something has gone wrong ... But now the important question: Did adding that ctrl-z actually solve the problem ? You did not mention anything about it. Regards, Rudy Wieser -- Origional message: schreef in berichtnieuws ...

*+-One drawback though : If, for whatever reason whatsoever, the CSV contains a
*+-ctrl-z somewhere in the middle you will throw the remainder of the file I'm up to my waist in alligators.. but I did another looksee and saw the disk I thought damaged was the same size and some unzip programs think the file is corrupt and won't open it and others will only give me half the file. One other clue, GNU tail won't work, but on the full-sized file, grep finds everything. Which unzipper do you prefer?
