Access to the path is denied.

Question

trivial error, time performs the normal process of deleting files and another hour to perform the same process I get this error.

This is an update of a website folder that is being accessed through IIS, then this process occurs while people are logged on the website.

You have no idea what can be?

Exception.Message =

There are any number of reasons why you'd get that exception, but without knowing more about what's going on, it's impossible to say. Could be that if the file was uploaded via IIS, then IIS might still have a handle on it. Are you sure you disposed of any streams or file access?

Either way, I would wrap the attempt to delete the file in a try/catch block, and log any failures. That way, your application won't crash, and you can easily see what files are causing problems. Could be that next time it tries to delete, it will work. Depends on how long the file is being held.

As I said, without more background, we can't say, but the try/catch is something you should always do in a case like this, so I would add that and see how you get on.

Hope that helps.
