Size limit to the .txt files generated during the VI data acquisition

[Amanmeet]

Hi,

 I am acquiring analog voltage data using the NI PCI 6229 and use the corresponding VI program to acquire it to the computer. I am saving the data as a .txt file. When I have an acquisition session too long (~>10 minutes) I end up getting no .txt file and no error message is generated. A file is generated in smaller cases aprrox. 5 minutes acquisition.

I am wondering that, is there a limit the maximum size .txt file that can be generated from a VI. Or is there a better solution to save large data sets in real time.

What functions are you using for your DAQ and for your file saving?

To get some real help, please post your VI so we can see what you're doing and see if we can replicate it.
