Dropbox Not Syncing Windows 10

Dropbox, one of the most used cloud storage services (Google Drive, OneDrive), allows you to upload files to the cloud and then you are able to access them anywhere on any of your devices including Mac, PC, iPhone or Android devices.


In Windows operating system, you use Dropbox to back up files so you can recover your data when the hard drive crashes or other computer accidents happen.

However, many Windows 10 users have reported that they encountered some problems, including Dropbox not updating shared folder, Dropbox stuck syncing, Dropbox not connecting, etc. The serious issue is Dropbox not syncing files or folders.

Actually, the Dropbox sync issue is very common, just like Google Drive not syncing Windows 10. Why isn’t Dropbox syncing? The main causes are misconfigurations and bugs in settings, file in use, identical names, firewall issues, Proxy settings, etc.

If your Dropbox won’t sync files or folders, you come to the right place since we will show you some useful methods to fix the issue of Dropbox files not syncing in Windows 10.

Fixes for Windows 10 Dropbox Not Syncing

As with all troubleshooting, we will start with some basic checks and then work towards some complex methods. Try them one by one if Dropbox stopped syncing.

Solution 1: Restart the Dropbox Process

The first thing you should do is to check whether the Dropbox process is running on your computer. Sometimes, the Dropbox process isn’t running or responding or has frozen up, which causes the sync issue. In most cases, you can simply start or restart the Dropbox process, which is sufficient to solve Dropbox folder not syncing.

Step 1: In Windows 10, go to Task Manager.

If the restart couldn’t help, try other ways.

Solution 2: Check the File

If the file is open in an application, it cannot be copied from the Dropbox folder on your PC to the cloud server. Dropbox will not sync the file and you may receive the error message - file is in use.

To fix the sync problem of Dropbox, follow these tips to make a check:

  1. Make sure the file you need to upload or sync is not open on your computer.
  2. Check the file name and ensure it doesn’t contain any characters, for example, %, ?, #, &, etc.
  3. Delete the file from the Dropbox folder and copy a new version.

Solution 3: Clear Dropbox Cache

Full Dropbox caches might also cause the client to be not syncing files or folders. To fix the issue, you should empty the cache.

  1. Open Windows 10 File Explorer and go to the Dropbox folder.
  2. Locate to the .dropbox.cache folder.
  3. Choose all the files in that folder to delete.

Solution 4: Use Selective Sync

In Dropbox, there is a feature called Selective Sync that enables you to choose files or folders you want to back up. If you enable this feature, it will only sync the selective files. If you don’t add certain files or folders, you may find Dropbox is not syncing your files.

Try these steps to fix your issue:

  1. Click the Dropbox icon in the taskbar.
  2. Click the Settings button, go to Preferences > Sync.
  3. Click Selective Sync to put the files you want to sync into the selective sync folder. Also, you can unselect files that you don’t need.

Solution 5: Make Sure the Internet Connection

Internet connection is the basic to ensure the normal work of Dropbox. If the PC isn’t connected to the Internet, obviously, Dropbox stopped syncing. So, you should ensure the Internet is connected. In addition, you should keep enough network speed and do not limit Dropbox download and upload rate.

Learn how to troubleshoot Internet connection problems with these 11 tips incl. WiFi connected but no Internet Windows 10, router not connecting to Internet.

Tip: To ensure the download and upload are not limited, go to Dropbox settings > Preferences > Bandwidth and check Don’t limit.

Solution 6: Disable Your Antivirus Software

Your antivirus program like Windows Defender, Norton, AVG, etc. may regard the Dropbox application as a dangerous software; as a result, it stops Dropbox from syncing.

If you are bothered by Dropbox files not syncing, you should remove it from the antivirus program’s blacklist or disable the antivirus software temporarily. Then, you can sync your files with Dropbox again.

Solution 7: Grant Access in Firewall

In Windows 10, Windows Firewall may block Dropbox and then the sync problem happens. In this case, you don’t need to turn off the Firewall but you can add this application to the exception list to allow access.

The Windows Firewall may prevent your program from access the Internet. This post shows you how to allow a program through Firewall Windows 10.

Step 1: Go to the Allow apps window.

  1. Input firewall in the search box and then click Windows Defender Firewall. Then, click the Allow an app or feature through Windows Defender Firewall

Step 3: Click OK to save the change.

Solution 8: Adjust Dropbox Settings (for Advanced Users)

If you have tried the above methods but they don’t work to fix the issue of Dropbox not syncing files/folders, perhaps the problem is caused by incorrect configurations or modified settings. So, you should adjust Dropbox settings by following the steps below.

Here is what you should do:

Step 1: Click the Dropbox icon in the system tray, go to Settings (gear icon in the notifications panel) and choose Exit Dropbox.

Step 2: Input cmd in the Windows 10’s search bar, right-click Command Prompt and click Run as administrator.

icacls “%HOMEPATH%Dropbox” /grant “%USERNAME%”:(F) /T

icacls '%APPDATA%Dropbox' /grant '%USERNAME%':(F) /T

icacls '%LOCALAPPDATA%Dropbox' /grant '%USERNAME%':F /T

icacls '%PROGRAMFILES%Dropbox' /grant '%USERNAME%':F /T

Tip: If your Dropbox folder’s location isn’t the path: C:UsersYourUserDropbox, change the first command to point to it, for example, icacls “D:Dropbox” /grant “%USERNAME%”:(F) /T. Note that you should let other commands keep unchanged. Besides, wait patiently since the operations may take some time to finish based on the size of your Dropbox.
