What is XDUPE

XDupe is a extend FTP feature for the server, it saves your time when you uploading files by fast skipping "dupes".

What is the "dupes"

the "dupes" we called is the same files which have been uploaded to the same remote directory or exists in FTP server's file database.

Why need the XDUPE feature

For example, you are using a FTP client or FXP client and trying to uploading a whole directory to the target server, but now there are 9 users doing the same thing as you. when you transferred the first file, you may get a server response as below:

STOR blabla.r02
553- X-DUPE: blabla.rar
553- X-DUPE: blabla.r03
553- X-DUPE: blabla.r06
553- blabla.r02: This file looks like a dupe!
553- It was uploaded by someone(0m 20s ago).

Good luck! you will get this response again and again without XDUPE! it wastes your time and maybe you can't uploading files anymore, because of all of them are dupes which have been uploaded by other users.

How does it work

The bad thing is that your FTP clients has no such XDUPE feature, but the good news is FTPRush already supports it! When you get the same 553 dupe response from server, our FTP client grabs the response lines, and removes these dupe files from your transferring queue.

How to Enable XDUPE option in FTP client

Start FTPRush and hits F3 key to show the Site Manager dialog, selects the site you want to changing and double click it to show the Site Properties dialog, then checked the "enable XDUPE" option.
