Error 5 occurred at Delete

[Tui]

I have a simple VI that truncates a text file, but I get the error "Error 5 occurred at Delete" when it runs

Any takers?

Hello Tui.
Your Truncate...VI should not be the problem. A good candidate for your error might be the code that wirtes to the LogFile: Is it possible that this code and your Truncate...VI run at the same time?
This would match Error.Code=5.

Hi Guenter

I don't see how my write code (enclosed)could be the problem as I close the file.

Have tried with time delays, but that made no difference

Hello Tui.
Now I see it: You currently do not close the file in the inner case structure's "False" case of your TruncateLogFile.VI.

Thank You,

Sometimes the easy mistakes are hard to spot.
