file size refresh rate windows 7

[Blueprint]

Hi guys,

I am using the File/directory info Vi to actively monitor the size of a file that is being downloaded for the purpose of showing progress to the user.

This has worked just as inteded for some years(!) but now that i am using windows 7 it seems that the file size is not updated as quickly as before.

If I press F5 in the folder where the file is downloaded, however, I will get the File/directory VI to also show the updated file size. 

Anyone have some thoughts on this?

Thanks in advance!

This is most likely a windows issue, and is closer discussed here.

It is also mentioned some fixes. Have not tried them, but some other claims that they work.

Some claims that it is unsolvable, but I have not read the entire thread.

has anyone found a solution to this problem? still seems to be an issue for me (win 7 32 bit pro), forums are vague and none of the fixes I could find work for me.

I don't know if this was ever resolved, but I wrote a little script that will launch a new explorer window based on the directory path you input.  It then refreshes the directory view, then closes the window.  My data logging program can now be programatically update the size of the log file.  Unfortunately this opens up a new window every 5 seconds (the update rate), then closes it.  The other frame simply has indicators for the Reference Out and the Error Out data.

There must be a better way...

Hi!

You can use the Get File Size function, I have attached an example file below and a snippet for easier viewing.

It is also possible to execute a Windows command line from the System Exec function, giving you the option to run silently (minimized). Have a look at this KB for more information: http://digital.ni.com/public.nsf/allkb/8E19CA81874FFDD786256BE40066C151

Best regards,

That worked perfectly.  Thank you.
