Indy Installed now FTP question

I am using the following line to get a file from the FTP site.

idFTPNJMLS.Get(njmls_files[i], local_file, true, true);

The only problem I am running into if it goes to download the file and
it already exists it errors. I thought that when I wrote the above line
that it would overwrite.

Remote File: njmls_files[i]
Local File: local_file
OverWrite: true
Resume: true

Do I have the wrong syntax?

Any help is appreciated! Thank you all.
