Hi,

There are 2 overloads for this method. One with 3 and one with 4 parameters.

I think you want to use the one with 3 parameters.

As you can see in the documentation there is a 3rd parameter named BackupOfFileToReplace

By the way if you want to copy a file you can also use

File.Copy(source, destination, true);

Here the third parameter indicates that if destination file exists it'll be overwritten

You can also use File.Copy(source,destination) but if the destination file exists it'll not be overwritten.
