Save bin file over 4GB limit

[kwjae92]

Hi, I allocated buffer to save array data over 4GB and I want to save array by bin file.

I used write to bin file and it has limit 4GB, so I can't save whole my data.

Can I save bin file over 4GB in labview?

I use Labview 2015.

Thanks.

more interesting than your labview version would be the bitness of your labview version.

could you not split files after a certain size (e.g. start a new file)?

File sizes should not be limited. The internal array size does have limits.

What errors do you get?

Not likely.  Definitely not with LabVIEW 32-bit.  You might be able to have it all with 64-bit LabVIEW and a 64-bit OS.

Generally if you want to save a file that large you log to the file as the data is coming in.  That saves A LOT of memory.  The file size is limited by an I64, so you should not have any issues there.

I agree.

While the Read/Write spreadsheet file functions are limited to an I32 byte offset (that should be fixed ) the binary files should permit files large than 4 GB.

I am certain files over 4 GB can be read, but unfortunately, I deleted any temp files that I created that large so I have to trust my memory I have written files over 4GB.
