☑Check the date and time on your device
If your device has the incorrect date and/or time, it may be unable to connect to Dropbox in order to sync your files.
☑Check your accounts
You can log in to multiple accounts on the same device, so if you’re missing a file that should have synced, make sure you’re on the right account.

☑Check your sync status
If your files and folders are different across your devices, you can check your sync status. You can also make sure selective sync hasn’t removed folders from your device.
☑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.

☑Make sure you’ve saved your file to Dropbox
Search your computer for the file with the search bar in your taskbar (Windows) or Spotlight in your menu bar (Mac). If it’s not in Dropbox or a connected app, it won't sync with Dropbox.

☑Check whether you’ve joined a shared folder

☑Make sure others haven’t changed or moved your file

☑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.
