Insufficient memory to perform operation

[al capern]

When trying to open large Tab demited text files (70Mb - 370Mb) using the "Read from Spreadsheet file" vi I recieve a message stating that there is "Memory is full" followed by "insufficient memory to perform operation" . It is strange because these files open normally with excel. I get the same fault irrespective of the  VI used to read from the text file .  Please note that the code simply reads and displays with no other operations taking place.   Any ideas please.

Hi caperng,

have you read through the KB articles provided by muks?

Let's do some calculations with your 370MB text file:

- loading the file into a string: takes 370MB

- converting the string to an array: takes (at minimum) another 370MB chunk of memory (yes, "Spreadsheet string to array" takes a lot of memory!!!)

- displaying the array in an indicator: takes (at minimum) another 370MB chunk of memory (each indicator has it's own copy of the data!)

So:

"code simply reads and displays" a 370MB textfile takes (at minimum) 1110MB of memory...
