Fixes for Windows 10 Dropbox Not Syncing

Solution 1: Restart the Dropbox Process

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.

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.
