How to fix Dropbox not syncing and other issues
The information in this article applies to all Dropbox users, unless otherwise stated.
This article covers fixes for Dropbox sync issues and troubleshooting steps. Try the steps below if:
- Updates to your files aren’t syncing with people you share with
- Updates to your files aren’t reflecting in your own account on dropbox.com
- New files added by other people or devices aren’t syncing to your device
- The number of files syncing seems to be “stuck”
- You see errors about particular files
Note: If your device has an unreliable internet connection or a file is very large, it may take longer for Dropbox to sync. You can wait a few minutes for Dropbox to catch up. If that doesn’t work, try the steps below.
Dropbox is stuck syncing forever, waiting to sync, or not starting
If your Dropbox desktop app is stuck syncing, waiting to sync, or not starting to sync, it may be due to your network settings or firewall:
Errors about low disk space on your computer or hard drive
Dropbox has a few different tools for helping to manage your disk space on your device.
If you want to remove files from your hard drive without deleting them from your Dropbox account, you can make those files online-only or use selective sync to choose which Dropbox folders sync to your hard drive.
If you want to remove files from the Dropbox desktop app and the rest of your Dropbox account, you can either:
- Delete the file from your Dropbox folder or dropbox.com.
- Move the file out of your Dropbox folder and into a local folder on your hard drive.
Can’t move, open, or delete a file or folder from the Dropbox folder
If you can’t make changes to a file or folder in your Dropbox folder, the first thing to confirm is whether the file is visible and can be edited on dropbox.com.
Some applications will put restrictions in place that can prevent other applications (like Dropbox) from accessing your files while that other application has them open. This is to prevent conflicts between the two.
If, after you’ve saved your file or quit the application you’re using, you’re seeing errors about that particular file, or it never seems to finish syncing, you may want to restart your computer in case a crashed or background application is accessing your files in a way that prevents Dropbox from syncing your changes.
If you can’t see and edit your file on dropbox.com, the file may not be properly synced. Try these other troubleshooting steps below to resolve issues with the Dropbox desktop app syncing, starting with checking connectivity:
Files are marked as “up to date” but are not
If either dropbox.com or the desktop app is showing your files as being up to date but changes you’ve made aren’t appearing, it typically means one of two things:
- Your desktop app hasn’t yet uploaded the changes to your account on dropbox.com.
- Your desktop app hasn’t yet downloaded changes made in your account on dropbox.com.
Usually, this will update automatically and you’ll simply need to wait for the files to finish syncing. If the desktop app doesn’t appear to be syncing, try the following troubleshooting steps:
File couldn’t sync due to a hardware issue or file corruption
If Dropbox encounters errors while trying to read or write a file, there may be an issue with your desktop OS or hardware. You can use disk diagnostic and repair utilities to identify and repair errors:
- Windows: Use Check Disk (chkdsk).
- macOS: Use Disk Utility.
How to check for disk errors
Important:
- You must have administrator privileges to run chkdsk.
- Interrupting chkdsk isn’t recommended.
- The time it takes to run chkdsk depends on the size and speed of your drive, amount of data stored, and presence of potential errors.
How to run the Check Disk (chkdsk) utility on Windows
- Type “cmd” or “command prompt” in your taskbar’s search field.
- Right-click Command Prompt in the Start menu.
- Click Run as administrator.
- Scan for problems by typing “chkdsk” and pressing Enter.
- Repair problems by typing “chkdsk /r” and pressing Enter.
Important:
- You must have administrator privileges to run Disk Utility.
- Interrupting Disk Utility isn’t recommended.
- The time it takes to run Disk Utility depends on the size and speed of your drive, amount of data stored, and presence of potential errors.
How to run Disk Utility on macOS
- Click Launchpad in the Dock and type “Disk Utility” in the search field.
- Click the Disk Utility icon (stethoscope on hard drive).
- Select a volume in the left sidebar, and click First Aid.
- Scan for problems by clicking Run.
- Repair problems by clicking Repair Disk, Verify Disk.
Note: If the disk health check reports an error, double check your hardware and consider replacing it. You can also try replacing the corrupt file. Try opening the corrupt file to see if everything looks correct. If past edits to the local file were successfully synced to dropbox.com, you can attempt replacing the local file by downloading its online version. Learn how to recover older versions of files.
Folder couldn’t sync because it was blocked by antivirus software
If desktop syncing is blocked because your antivirus software identifies a threat, the following options are available:
- Delete the file.
- Quarantine the file.
- Allowing your antivirus software to move the infected file to a secure location on your hard drive isolates the file from the rest of your system.
- Allow the file to be downloaded normally.
Important: Exercise caution when overriding your virus scanner. Only allow the file to be downloaded normally if you’re sure the flagged file isn’t a threat.
If the scenarios above don’t match your issue, try the troubleshooting steps below.
Dropbox not syncing after login
If you‘re using encrypted team folders and have logged out of your Dropbox account, you need to be granted access to the encrypted folders again when you log back in.
Syncing will pause and the sync status in the Dropbox desktop app will show Requesting access to encrypted folders… until you’re granted access. Learn how to check your sync status.
If you’re a team member, you can do one of the following:
- Ask another team member with access to the encrypted folder to open the Dropbox desktop app on their computer. This automatically resolves the issue.
- Contact your team admin to resolve the issue.
If you’re a team admin, you can resolve the issue by doing the following:
- Log in to dropbox.com with their admin credentials.
- Click Admin console in the left sidebar.
- Click Settings in the left sidebar.
- Select Advanced data protection.
- Click Device enrollment interrupted.
- Entering a backup key.

☑Keep the Dropbox desktop app open
- If you added a file to the Dropbox folder on your computer, you must keep the Dropbox app running to sync it to the rest of your Dropbox account.
- Once your files are synced across your devices, you can close the Dropbox desktop app on your computer.
☑Close your other applications
If you have one of your Dropbox files open in another application, like Microsoft Word, your file might not sync properly. Close all non-Dropbox applications, then close and re-open the file in Dropbox.
☑Check your file names
Certain special characters, like “*” (asterisk) or “/” (forward slash), aren’t compatible with all devices. Remove any special characters in your filenames.

☑Check the number and size of the files stored in your Dropbox account
The number of files you can store in your Dropbox account is limited by your available storage space. If you run out of space in your account, consider upgrading your plan or deleting files or folders.
Files uploaded through the desktop app or mobile apps must be 2 TB or smaller and files uploaded to dropbox.com must be 50 GB or smaller.
All files uploaded to your Dropbox account must be smaller than the amount of storage space you have. For example, if your account has a storage quota of 2 GB, you can upload one 2 GB file or many files that add up to 2 GB. If you’re over your storage quota, Dropbox will stop syncing.
Note: Files uploaded through the API must be 350 GB or smaller.

You may have to enter proxy server information, connect to a LAN (local area network), or manually set the network to allow the “*.dropbox domain.”
Learn more about which domains Dropbox uses.
If none of these fix the problem, check with an admin.
☑Check your file type
Dropbox can’t sync some kinds of files. These include:
- Files with certain suffixes, such as files that end in:
- desktop.ini
- thumbs.db
- .ds_store
- icon\r
- .dropbox
- .dropbox.attr
- Temporary files:
- These are created by applications like PowerPoint and Word, and often start with a ~$ (a tilde and dollar sign) or .~ (a period and a tilde).
- Certain types of files and metadata, including:
- Symbolic links (Symlinks)
- Shortcuts
- Junction points
- Resource forks
- Networked folders
- Extended attributes
- Suspicious files:
- If you get an error message that says permission has been denied or that your file has been rejected by the server, Dropbox may have flagged the file as a copyright violation, DMCA violation, or malware.
- If you suspect this is the problem, contact support.
☑Troubleshoot your external hard drive
- If the files you want to sync are on an external hard drive, make sure the external hard drive is connected and recognized by your computer.
- If your hard drive is connected and recognized but your files won’t sync to Dropbox, move the Dropbox folder back to your computer temporarily to see if the external hard drive is causing the issue.
Note: Storing the Dropbox folder on an external drive is no longer supported on computers running the updated version of Dropbox for macOS on File Provider.
☑Make sure your app syncs changes automatically
Some non-Dropbox applications save changes automatically. However, if you edit a file in an application that doesn’t save changes automatically, you’ll need to save your changes manually by re-adding your file.
Learn how to add files to Dropbox.
☑Check that the file isn’t read-only or locked
If your file is read-only or is locked by a non-Dropbox application, you can’t sync your file to Dropbox.
- If you’re on Windows: See if your file is read-only in your file properties and uncheck that option.
- If you’re on a Mac: Check if your file is locked in your file info and unlock it.
If the file has a lock icon on it, it was locked with Dropbox. Learn how to unlock your files.
☑Update or reinstall non-Dropbox applications
If you use a non-Dropbox application to edit your files, make sure the application is up to date. You can also uninstall and reinstall it, then check to see if your file syncs to Dropbox.
