automatic change file to store data

[norak]

Hi,

I have a stand-alone system working with 7 serial ports.

I need to store a huge amount of data ( 115.200 Kbaud / port ) because the system must keep working during a week.

In two days I have a file size of more than 500Mbytes. The problem is that I am storing the data in a .txt file and then, when i want to process the data, the notebook can´t open a file with so size.

I can´t find a way in which the vi can change in real time (itself) the file to store the data.
Maybe the way is create the 3-4 files before the while loop (in which i read the data) and then change the file in which i store the data, but I can´t find a way to do this. With the get_file_size.vi i know when i must change the file, but how do i to do this without get out the while loop? I think is necessary to keep the visa_read.vi working...

or maybe another format or way to store data is better?

It doesnt matter to lose data while changing the file.

Does anybody any idea?

Thanks

Another option could be to have a case statement that, when the file is too large, closes the existing file and creates a new file? (see the attached screenshot)
