When you use Dropbox to sync files, you may encounter a situation - Dropbox files not uploading. If you want to know what causes this problem and how to fix it, you are in the right place.
Many reasons would result in Dropbox not uploading photos, videos, and other files. Here are some common ones.
Since there are many causes for Dropbox not uploading files, the solutions are also correspondingly different. Please choose the appropriate solution according to your situation.
A stable internet connection is essential to keep Dropbox running. If your device is not connected to the network, or if the network connection is unstable, the file upload will undoubtedly fail. LAN congestion, wireless LAN interference, hardware configuration, etc. may cause poor network quality. You can do the following to improve network quality.
➯On a wireless network - Get closer to the wireless access point; Check if other devices on the network are performing heavy downloads or uploads; make sure the network cables are plugged in.
➯On a wired network - If there are heavy downloads or uploads on the network from other devices, use it later; Ensure that the router or modem has the latest firmware available; make sure the network cables are plugged in.
Although Dropbox allows you to upload various types of files, it has restrictions on the names of the files. You can check whether there is a problem with your file name from the following two aspects.
Sometimes, your firewall or anti-virus software will also prevent Dropbox from running correctly, resulting in Dropbox not syncing files. Also, if you are running OneDrive and Dropbox at the same time, Dropbox's file upload may have interfered, as we encountered earlier with the error - can't backup to both OneDrive and Dropbox.
To solve this problem, please add your Dropbox to the firewall whitelist and make sure that you will not receive interference from other programs while running Dropbox.
Step 1. Head to Windows Settings, and go to Update & Security > Windows Security.
Step 2. Click on Firewall & network protection, then tap Allow an app through the firewall.
Step 3. Hit Change settings, and tick Dropbox under Private and Public. Click OK.
When you run Dropbox, it will automatically generate cache files on your device so that the next time the program starts and runs faster. However, if the cache file is corrupted, it could also be the reason why your Dropbox files are not syncing properly. You can follow the steps below to remove cached data and resume Dropbox uploads.
Step 1. Press the Windows + E keys to open Windows Explorer.
Step 2. Copy the %HOMEPATH%\Dropbox\.dropbox.cache code in the address bar to open the Dropbox cache folder.
Step 3. Select the cached folder, and right-click to choose Delete.
The file upload speed of Dropbox is related to broadband, and by default, Dropbox limits bandwidth. If you experience the problem of can’t upload to Dropbox, Dropbox not uploading large files, or Dropbox syncing slow, you can turn off the bandwidth limit.
Step 1. Click Dropbox in the taskbar, click the gear icon and choose Preferences.
Step 2. Tap the Bandwidth tab. Choose Don’t limit under Download and Upload Rate, then click Apply.
When you use a proxy server to connect to Dropbox, it may not be able to connect properly, causing Dropbox sync issues.
Step 1. Open your Dropbox desktop app preferences.
Step 2. Click the Proxies tab, and switch to No Proxy in the Proxy settings. And click OK to confirm it.
In most cases, restarting the Dropbox program can resolve sync errors such as Dropbox not uploading folders and files.
Please see if your Dropbox has enough storage space available for your uploads. If the size of the uploaded file exceeds the remaining free space in Dropbox, the file upload will fail for sure. You can upgrade Dropbox storage or free up space on Dropbox by deleting files or folders.
In addition to enough Dropbox storage space, you also need plenty of local space for the Dropbox program to run correctly. If your hard drive is overloaded, Dropbox files not uploading may occur. You can use the disk cleanup tool to free up storage space in the following steps.
Step 1. Type “disk cleanup” in the search box on the taskbar, then select Disk Cleanup from the list of results.
Step 2. Pick the drive you want to clean up, and then click OK.
Step 3. Check the items to get rid of under Files to delete, tap OK, and then click Delete Files.
Dropbox comes with a selective sync feature where you can choose to only sync specific folders and keep others offline on your computer. Maybe that's why Dropbox won't upload files and folders.
Step 1. Go to Dropbox Preferences, and click Sync > Selective Sync.
Step 2. Uncheck the folders you don't which to sync to your computer in the next popup, and click Update.
