How can LabView's file size vi with I64 still cannot read file size larger than 4.2GB

[BryanL]

I am trying to read file sizes using the get file/directory info vi but got incorrect file sizes if the files are larger than 4.2-4.3 GB.  I am using LabView 8.2 and Windows XP. I wonder anyone has seen the same problem?

Regards,

This seems to be a bug in 8.20 and lower. It works fine in 8.2.1. 🙂

Quote from the LabVIEW 8.2.1 Bug Fix Information:

406GLS7U

Fixed an issue where the File/Directory Info function returns an incorrect size for files larger than 4 GB.

Thanks Altenbach, looks like we need to upgrade LV again.

Since there is this bug preventing us to get correct file size on files larger than 4GB with LabVIEW 8.20, I wonder if anyone has built a vi to call the GetFileSizeEx function with windows user32.dll call? Thanks in advance if you could post.

GetFileSizeEx is a function in Kernel32.dll instead of user32.dll. Sorry for the mistake.
