Dukto R6

Dukto is one of my long-lived software project, it’s now at the 6th release, with many improvements over the previous versions. One of the main changes of this release is the new user interface inspired to the Metro style UI developed by Microsoft for the new releases of Windows Phone, Windows, Xbox and all the other Microsoft products. Since I like the simplicity, the essentiality of this kind of UI, I’ve decided to make a new Dukto interface for all the supported platforms.

If you don’t know Dukto, I can tell you that it’s an easy file transfer tool designed for LAN use. I use it in my everyday work to transfer files from one PC (or other device) to another, without worrying about users, permissions, operating systems, protocols, clients, servers and so on… Just start Dukto on the two PCs and transfer files and folders by dragging onto its window. That’s all.

Dukto main features are:

  • Simple user interface
  • No server or internet connection needed
  • Zero configuration
  • Clients auto-discovery
  • High speed file transfer
  • Multi-OS native support
  • Portable version available
  • Multi files and folders transfer
  • Transfers log
  • Send and receive text snippets (eg. useful for sending URLs)
  • Open received files directly from the application
  • Windows 7 taskbar integration with progress and transfer indicator
  • Show your IP addresses on the IP connection page
  • Full Unicode support
  • Metro style UI
  • Free and open source

Dukto is a free open source project, licensed under GPL. Official releases are made by me for the folliwing platforms:

  • Windows (XP or later)
  • OS X (10.6.x or later)
  • Linux (packaged for Ubuntu and Fedora)
  • Symbian (for Nokia touch phones)

Also there are porting made by other developers, like the following:

You can find the source code on the project page http://sourceforge.net/projects/dukto/ at SourceForge.net. Dukto has also been tested and certified by Softpedia, Brothersoft and GearDownload.

  • Just tried the program with two Linux PC’s and worked great!
    Congratulations, well done!!!
    I was so impressed that I tried to use it on my phone unfortunately the program is not starting…
    I have an android phone version 7,0. Is this because the latest android version? kind of compatibility problem?
    Would be wonderful if you can solve this issue.
    Keep up the good work!

  • Ciao,
    I am using Dukto on my PC & iPhone and I would like to know:
    – is Dukto using existing protocol(s) for the file transfer or you developed a specific one?
    – what ports must be open in your LAN in order for Dukto to work?

    Nazareno19 maggio 2017
  • @Nazareno ciao! Dukto is using a custom protocol designed purposely for this app, and works on port 4644 both TCP and UDP.

  • Hey, so Dukto has been the one reliable file transfer and text sharing across all my systems for years… thanks!
    Quick feature request to make it even better on Android: could we get the app to appear in the standard Share dialog?
    Keep up the great work!

  • Impressive! Definitely the BEST LAN file-sharing software! I like the design very much.

    To make it perfect, I suggest three modifications to be made in the next version :

    1. Allow users to set the dukto start up when the system boots. Then I don’t have to move to another device and manually launch dukto, and then come back to start the transfer.

    2. When user clicks close button X in the main windows, let dukto minimize to the tray and run in background.

    3. Improve the dukto protocol and implementation to make it faster. Currently, it can only utilize half of the bandwidth. On my switched Gigabyte-LAN, the transfer speed max is about 50-60MB/s, it is good, but it can be faster. The SMB runs at 110-120MB/s.

    I read the source code duktoprotocal.cpp and found the problem might be a single thread is responsible for reading data from file and then write data into the socket buffer. I tried to modify it by myself, but I’m not familiar with C++ and Qt, so I only increased the 10000-byte const in void Dukto:sendData(qint64 b) to 320000. And I also enabled Jumbo-frame feature in my network card. This way, I can increase the speed to 100MB/s. My approach is not elegant, but there is still room for improvement. I hope you can make dukto faster.

    I am glad to hear from you.

    Thank you very much!

  • Sir,
    As far as the speed and easiness concerned, Dukto R6 is the greatest of all.
    Thank you for your dedication and hardwork.
    I failed to reach this app early.
    So, to all, download and use Dukto R6.
    This is invaluable.

  • I can’t add more items on ‘sending’ queue while I am already sending a file.I have to wait for transfer to complete.So please add a
    feature so that I can ‘drag and drop’ a file while transfer is already in progress.

    1) I think it would be great if I can add more files/folder in sending queue. So that I won’t have to wait for the transfer to complete and then transfer other file.

    2) And an option for pausing the transfer would be nice.

  • Just a feature request for the android app, the “share to” feature is very neat and works with most apps but not dukto would be great when you need the to send an image from the gallery app to dukto but dont want to browse around in the dukto file browser
