Hi
I am using the following code to delete all the files from a folder but it doesn't seem to work

        Dim MYDOC_DIR As String = Environ("userprofile") & "\My Documents"
        Dim TEMP_IMAGES As String = MYDOC_DIR & "\Temp_Images"

        Dim myDirInfo As System.IO.DirectoryInfo = New DirectoryInfo(TEMP_IMAGES)

        For Each file As FileInfo In myDirInfo.GetFiles()
            file.Delete()
        Next
        For Each dir As DirectoryInfo In myDirInfo.GetDirectories()
            dir.Delete(True)
        Next

So what does happen? Do you get an exception thrown, or something else?

sounds like you don't have permission to delete the user profile

Do not use stuff like Environ("userprofile") & "\My Documents" when you want to access a standard directory. There are too many variations between different versions of Windows, different languages, and the possibility for a user to change the name or location of a standard directory.

It is safer to use the following instead. It will give you the right location no matter the situation:

System.Environment.GetFolderPath(environment.SpecialFolder.MyDocuments)

Note that SpecialFolders provides a list of all the standard directories.

Thanks very much James. That did the trick. I have used the previous code all over my apps so glad that you short circuited future user errors.
