Answer 1

File.Copy(source,destination,true) will overwrite destination if permissions allow. See the docs.

Answer 2

have you tried File.Copy(src, dest, true). This might help overwriting the existing file.

Answer 3

Check the write permission is allowed for the folder contains the destination file.

Try the following:

System.IO.File.Copy(src, dst, true);

true if you want the existing file will be overwritten.
