Large File Splitter

[Kas]

Hello.

I'm trying to implement a large binary file splitter. With relatively small files (>200 MB), this seems to work ok. But with large files (<1 Gb), it fails. Randomly, I see a file being created with 0 KB size on it (attached picture). The problem seems to go away if I put a delay of 03s inside the loop, but anything less and the problem persists. I'm not sure if I'm doing something wrong (most likely) or if its a labview bug.

Thanks

No such error when I run it (3GB files even). I removed the wait function altogether. Running LV 2012f3 32 bit.

It's not just an update issue , if you hit F5 or reopen the directory the OS has not updated the number to its correct size?

Does it happen on a number of different files and sizes (above 1 GB)?

Just a general comment: There is no need to set your file position inside of the loop. The position increments during the read. After a read, the position will be set to the next byte, so the the next read will start where the previous left off.

Nice, that was it. I was monitoring the directory, but forgot to refresh. Everything seems to be there.

Thanks

Didn't know about this little trick. It certainly simplyfies things.

Thanks again.
