File Access: How do I use Qsync to synchronize files on my computers and NAS? (For Mac users)
Last Updated 5 years ago

Getting started

Qsync is a cloud based file synchronization service empowered by QNAP NAS. Simply add files to your local Qsync folder, and they will be available on your QNAP NAS and all its connected devices.

Before using Qsync

Follow the 3 steps below before deploying Qsync.
  1. Create user accounts on the NAS,
  2. Install Qsync Client on your computers and Qfile on your mobile devices.
  3. Log into the NAS (serving as a Qsync server) from your computers or mobile devices (referred to in this document as Qsync clients.)

Before using the Qsync Client utility, please check that your Mac meets the minimum system requirements:
Operating System: OS X El Capitan (10.11), OS X Yosemite (10.10), OS X Mavericks (10.9), OS X Mountain Lion (10.8).
RAM: 2 GB.

Create user account on the NAS

Please create user accounts for Qsync users.
As the NAS administrator, go to “Control Panel” > “Privilege Settings” > “Users” or go to “Qsync”>”Users”, and then click ”Create a User”.
Only NAS administrators can create accounts. If you are not an administrator please have the system administrator create an account for you.

Install Qsync Client utility

Qsync will synchronize all of the chosen files on your computers or mobile devices.
Follow the instructions on the “Overview” page to download the utility (log into the NAS, and then go to “Qsync Central Station 2.0” > Overview.)
Or download the utility from the QNAP website: Support > Download> Utilities.
For computers, please download the Qsync Client utility for Mac.
For mobile devices, please download and install Qfile for iOS or Android.

Log into the NAS

After installing the utility, enter the username and password and specify the designated NAS as the Qsync server.

To locate the NAS within a LAN environment, simply click “Search” to find it or key in its IP address or name. (e.g. IP address: or

To connect to a remote NAS (over the Internet), please use your myQNAPcloud address to log in. (e.g.

Note:If the ports have been changed for the NAS connection, please append the port number to the IP address; otherwise, please only enter an IP address. (Default port number: 8080)

Set up Synchronization folder pairs

Synchronize folder pairs between your folders on a Mac and your NAS. Click “Next” to proceed.

Note: To sync with a NAS shared folder, make sure that the NAS administrator has enabled synchronization on this shared folder. This setting can be modified at “Control Panel” > “Qsync Central Station 2.0” > “Shared Folders” on the NAS. After synchronization is enabled, users who have read and write privileges of this shared folder can sync its content with other devices. If the user only has read privileges to the shared folder, every time they add/change/delete a file in the paired local folder, no changes will be made on the NAS.

Click “Edit” to alter the sync folder location and configure Selective Synchronization:

Location: Choose the folder on your Mac to sync with your NAS folder. Selective Synchronization: Select only subfolders of the NAS folder to sync with Macs. This is useful when the size of the NAS folder is larger than the storage capacity of the Mac.

Start using Qsync Client

Click on the Qsync Client icon on the menu bar to bring up the menu.

Open the Qsync folder

Now, just copy or move your files to the local Qsync folder in one of your devices, the files will be copied to all your other devices (devices with Qsync installed and are connected to the NAS.)

From now on, you don’t need to copy files back and forth between your PC and external devices or worry about the size of the files as you to try to attach them to an E-mail.


There are a few methods you can synchronize your files. Qsync will automatically synchronize the files among your computers or mobile devices that have Qsync installed, and they will also be synchronized to the Qsync folder on the NAS.

  1. For PCs, drag and drop files directly to the local Qsync folder.
  2. For mobile devices (Qfile), copy or move files into the Qsync folder.
  3. For the NAS, copy or move files to the Qsync folder via File Station (web based file explorer).

    1. If files are “dragged and dropped” into the Qsync folder, they will be moved to the Qsync folder, as supposed to be copied into the folder, if the files and the Qsync folder are located in the same disk drive. The behavior is the same as File Explore in Windows.
    2. The maximum size of a single file that Qsync can transmit is 500G in a LAN.
    3. Qsync doesn’t support SAMBA, FTP or AFP for files access. Please access files using File Station or Qsync.
    4. Qfile can only synchronize the file list and does not download the files to a mobile device. Please download the files when you need them.

Offline editing

You can browse and edit your files offline, and once your device is online, Qsync will sync the files you edited offline for you automatically.


Share files by download links

You can share files by sending file download links to those who haven’t installed the Qsync Client utility.
  1. For Macs,right click on the file that you would like to share in the local Qsync folder and click on “Share the link.”
  2. Select to send the link via E-mail or copy the link to others.
  3. Click “Advanced” to check more options for the link, such as creating a SSL link, the expiration date, or password.

  4. For the NAS, right click on the file that you would like to share in the Qsync folder within File Station and click on “Share.”
  5. For mobile devices, launch Qfile to share the file in the Qsync folder by clicking the icon to the right and click “Share.”
  6. The file recipients can click on the link or copy and paste it to a web browser to download the file.

Share the folders with a group

You can share a folder with a group of users. If any member from the group shares the files in the folder, other members can receive the file.
  1. Create user accounts in the NAS for each group member.
  2. Have Qsync utility installed on each member’s device.
  3. Right click on the folder that you would like to share in the local Qsync folder and click on “Share this folder as a team folder.”

  4. Select users from the list of local or domain users.

  5. All members in the group will receive a file sharing invitation. Once accepted, the group members can start to access this shared folder..
  1. The team folder will take effect after the invited users accept their invitation.
  2. Users cannot share the team folders which are shared from others again.

Remote access

Access the NAS over the Internet

To connect to a remote NAS (over the Internet), the administrator must first configure the NAS device name in “myQNAPcloud” (Log into the NAS> NAS Desktop > Click on the myQNAPcloud shortcut.)

Next, inform users about the myQNAPcloud web address for their remote access. You can then use the myQNAPcloud address to log into the remote NAS. ( e.g.

  1. The connection with the NAS over the Internet will be slower compared to a LAN environment.
  2. As you switch back to a LAN environment where your NAS is located, please reconnect to the NAS via LAN, instead of the myQNAPcloud service for a better connection quality.
  3. For better performance on file transmission, it is recommended to configure port forwarding on the router if possible.

Sync photos and videos automatically

Qsync can sync your photos and videos on mobile devices to the Qsync folder of across all Qsync clients automatically..
  1. Follow the instructions on the “Overview” page to download the utility. (Log into the NAS, and then go to “Qsync Central Station 2.0” > “Overview.”)
  2. Launch Qfile,
  3. Click “Settings” on the bottom right side of the screen,
  4. Scroll down and look for “Auto upload from photo gallery” and click on “Set up now,"
  5. Select a NAS to upload photos and videos to,
  6. Select the folder,
  7. Select “Use default setting” ( /Qsync/Camera Uploads) or select “Set up manually” to set the path,
  8. Select if you want to upload all photos from photo gallery immediately,
  9. You can select “Wi-Fi only” to upload files through Wi-Fi and avoid possible expenses associated with the 3G Network,
  10. The uploaded files will be synced to the “Camera Uploads” folder under the Qsync folder on Qsync client devices.
Note: If files that were previously uploaded are deleted from the Camera Uploads folder, Qfile will not upload those copies to the photo library again.
