Setting a File Size Cap on program

[Wilk]

Hi, so i'm using LabVIEW 7.1 and simply recording same data using the Write to File VI. The program writes the desired data I need but I'm looking to set up a File Size Cap or Limit when writing the data so the recording would stop once it reached a certain size, like 1 gigabyte. Problem I'm worried about is someone using program, leaving it running, while it writes data till there's no more memory left on the hardrive. Also, is there a more effecient way to Write to File in spurts rather than continuous? It burns up the CPU when writing continulousy. Thanks

1.) For the file size, you can use the "get file size" vi.  It is in the advanced File I/O pallet.

2.) You could use master/slave loops (parallel while loops) to process your data.  The master loop would write the data to a queue, the slave loop would read the queue and write the data on some periodic basis.
