Quick Start Guide to USB syncing for doubleTwist Pro v3 [Win 7/8/10]

Quick Start Guide to USB syncing for doubleTwist Pro v3

doubleTwist Sync supports USB syncing for both USB Mass Storage (MSC) and USB MTP devices.

In general, very old Android devices offer USB MSC mode while newer devices offer USB MTP mode. Some devices, such as the Samsung Galaxy S2, offers both modes. The easiest way to tell the difference is that in USB MSC mode, your PC assigns the device a drive letter. In USB MTP mode, no drive letter is assigned and the device is seen as a "Portable Device" by Windows.

For purposes of syncing in doubleTwist Sync, there is no practical difference between the two modes.

  1. Install doubleTwist Pro v3 on your Android device.
  2. Install doubleTwist Sync on your PC.
  3. Making doubleTwist Sync icon always appear in notification area.
  4. Connecting your device using a USB cable.
  5. Item selection and syncing using doubleTwist Sync.
  6. Verifying synced items on device.


  1. Download and install doubleTwist Player v3 on your Android device. The Android screenshots may vary from device to device.

    1. Search for “doubleTwist Player” in the Google Play Store. Two results will appear, "doubleTwist Music & Podcast Player" and "doubleTwist Pro".

      The two versions are functionally the same, the only difference between the two is that one is a limited version with an in-app upgrade to doubleTwist Pro that unlocks full functionality while the other version is a paid version that is already unlocked with doubleTwist Pro fully activated. More information about upgrading to doubleTwist Pro from the limited version is available here.

      Select "doubleTwist Pro" to proceed with purchasing the app.
    2. Tap on the price to start the purchase process. You may need to enter your Play Store account password to proceed.
    3. Once the purchase has been validated, the installation process will continue.
    4. Tap on "OPEN" and then on "ALLOW" on the initial dialog so the app can access files on your device.
  2. Next, download the doubleTwist Sync installer.

    1. After downloading, run the installer. You may get a UAC warning screen. Click “Yes” to continue.
    2. The initial install screen will appear. Read the linked agreements and then click on the checkbox to signify your agreement. Then click on "Next” to continue.
    3. The installer will now download and install several components. This can take a very long time if your internet connection is very slow.
    4. After all components are downloaded and installed, the "ready to twist!" screen will appear. The two available options are to run doubleTwist Sync after installation and if doubleTwist Sync should automatically run when Windows is started. Click on “Finish” to exit the doubleTwist installer.
    5. Note: If you've enabled the "Always run on startup (recommended)" option but want to change this behavior after the installer exists, please see this 3rd party help page on how to change startup program behavior in Windows using msconfig.
  3. After the installer exits and doubleTwist Sync is first launched, the welcome screen will appear. Click on the "Ok, got it!" button at the bottom to dismiss this screen.

    1. By default, doubleTwist Sync will appear in the hidden notification area (system tray) of your PC.
    2. To alway see the doubleTwist icon, please click on "Customize..." in the hidden notification area (system tray).
    3. The "Notification Area Icon" control panel will appear. Change doubleTwist to "Show icon and notifications".
    4. The doubleTwist icon will now always show in the notification area (system tray).
  4. With doubleTwist Sync running, please attach your Android device to your PC using a USB cable. For best results, please only use the USB cable that the manufacturer supplied.

    1. A Windows AutoPlay dialog may appear when you connect your device. You can dismiss it without choosing any of the suggested actions by clicking on the "X" in the upper righthand corner.
    2. A doubleTwist Sync device window should now appear. Detailed information on each of the options can be found here. If it is a newer device, it may be connected in "USB Charge Only" mode instead of USB MTP mode. If it's connected in "USB Charge Only" mode, the hexagon chart in the doubleTwist Sync device window will be completely greyed out.
    3. You can switch modes by dragging down the Notification shade and then tapping on the USB notification. Then select the MTP option from the dialog that appears.
    4. Once USB MTP mode has been established, the hexagon chart in the doubleTwist Sync device window will now how much storage is used by music & pictures along free space.
    5. *** It is important that your PC recognizes your Android device and is able to access the storage locations on the device. If you can not copy a file/folder to the Android device using Windows File Explorer, doubleTwist Sync will not be able to sync to it either. ***

    6. *** Also, if you have a security lock on your device (PIN, Face, Pattern, or Password), USB MTP mode will fail if the lock screen activates. So for the duration of the sync, please do not let your device activate the lockscreen. You can either disable the security lock, set a very long time out period, or periodically tap on the screen to prevent the lock screen from activating. ***

    7. If your PC sees your Android device and you are able to browse the contents of the device from your PC but doubleTwist does not recognize it, please try the following troubleshooting steps:

      1. Reboot both the device and the PC.
      2. If doubleTwist Sync was running when the device plugged in, please try quitting and relaunching doubleTwist Sync with the device still attached.
      3. If doubleTwist Sync was launched after the device was attached. Please try leaving doubleTwist Sync running and then unplugging/replugging in the device.
    8. If those troubleshooting steps do not work, you may need to perform a full reset of doubleTwist on both your PC and Android device.
  5. doubleTwist Sync automatically scans your iTunes library, Windows Media Player library, and your Music folder for available media and playlists. If your iTunes library and playlists are not being imported properly, please try the steps listed in this iTunes XML troubleshooting page.

    1. In this example, iTunes has two albums and two playlists while Windows Media Player has a single album and playlist.
    2. Click on the "Music" tab. If your music library contains any DRM protected songs, you will see the warning dialog below.

      Prior to 2009, songs that were purchased from the iTunes Store were protected by Digital Rights Management (DRM), which limits playback to "authorized" devices. The iTunes Store has since converted to a DRM-free model and you can upgrade previously purchased songs to be non-DRM using a subscription to iTunes Match ($24.99/year). Please be sure to re-download all tracks to replace the protected versions with DRM-free versions.
    3. If you have a large iTunes library or a slow machine, doubleTwist Sync may take a few minutes to parse and import all of the information. Please be patient.
    4. You will then see the Music sync selection screen. You can choose what to sync to your device using playlists, artists, albums, or genres. More information about syncing can be found in the full doubleTwist Sync Guide. In this example, we are using playlists. All three playlists from iTunes and WMP have been selected.
    5. Click on "Sync now" and the sync will begin.
    6. Once the sync is complete, a results summary screen will appear.
    7. Click in the summary section to get additional details on the files just synced.
  6. As files are synced to your device, doubleTwist Pro will automatically add them to the library database.

    1. doubleTwist Pro will automatically index songs as they are transferred to your device. But the playlists will not be added until you disconnect the device from the PC.
    2. As soon as the device has been disconnected from the PC, the playlists will appear.
    3. If you have any questions about a specific feature of doubleTwist Sync, please see the full guide available here.
