Can you attach an example of a good and "naughty" data file? First thing I would do is open them in a plain text editor such as notepad.exe (with word wrap off) and compare them.

Dear jarvis24,

Thanks so much for the headsup. I've attached both normal and naughty output files here. I tried the notepad method you mentioned and found nothing in the naughty file though the naughty one (11.2kb) is as big as the normal one (11.3kb).

Is there any way to save the naughty one?

Great thanks!!!

I see what you mean. There is certainly content in the bad file--it's not empty--it just looks that way (at least on my machine there are MANY characters but they appears as if they were spaces). I tried many ways of deciphering what the hidden content. I'm wondering if it may have been damaged in transit somehow. Can you go to the original computer on which these data were collected and go directly to the data folder and open this file there? i.e., without moving or copying it anywhere? Both in Excel and Notepad/Wordpad if possible.
