MSBUild: Copy files with a name based on the original (following a pattern)

Question

I have a set of files inside a folder. They all have a name which matches the pattern DR__.*. I want to copy them to another folder, but removing the DR__ prefix. How can I do t

I agree with @Si's solution. But with MSBuild 4.0 you can do it with built in functionality. NAnt script is much clearer than mine. But I will add it as a solution just to show MSBuild 4.0 techniques:

    
       
    

    
         
            %(CVParameters.FileName)%(CVParameters.Extension)          
            DR__
            $(Prefix.Length)
            $(OriginalFileName.Length)
            $([MSBuild]::Subtract($(OriginalFileNameLength),$(PrefixLength)))
            $(OriginalFileName.Substring($(PrefixLength),$(SubstringLength)))
            $([System.IO.Path]::Combine($(DestinationDir),$(ModifiedFileName)))
                                                                                                                                                  

         
    

Edit (by OP): To get this working, I had to replace $(DestinationFullPath)in Copy with @(DestinationFullPath), to match the number of Source and Destination Files. Also, I had to change the prefix to DR__, since DR__. wouldn't work.
