How to check if a file is being used by another process.

[stimbo]

I don't know if this is available in the compact framework but there's a

DownloadDataCompletedEventArgs

class. Check to see if it exists under the Imports: System.Net

Think this example may help
MSDN

I think the webclient also has some features that may help like: IsBusy etc...

Alternatively, if none of that is helpful then you could as a rough work-around put it in a Try block and if an exception happens start a timer (without a message if you wish) to try again in a certain amount of time.
