No warning message when a user saves to a folder they don't have write access

[ukflix]

Hi

We have a folder in Cognos 10.2.1 which we have set to 'Deny Write' for the users.  However, when they create a new report and try to save to this location they don't get any error or warning, it just looks like the report has saved.  They then close the report and lose it because when they go to the folder, the report did not actually save.  Does anyone know if there is a way to make Cognos warn a user if they try to save to a location where they do not have Write Access please?

Thanks...
