Besides, another issue like Dropbox not syncing may disturb you while syncing data to Dropbox. First ensure your computer, phone, or tablet is connected to the Internet, signed in to the same Dropbox account, and the files or folders are located in the Dropbox folder. If all is right, please refer to the following solutions:
1. Rename the File name without these characters: / \ < > : “ | ? * . and shorter than 255 characters.
2. Do not sync some system files and temporary files like desktop.ini, thumbs.db, *.tmp, ~file, etc.
3. Change the file location to make the file components less than 300 components.
Dropbox Selective Sync might not work due to outdated software, insufficient permissions, corrupted cache, network issues, conflicts with other applications, configuration errors, account issues, or problematic file paths. Here are two easy solutions to fix it:
Solution 1: Restart the Dropbox sync process
Step 1. Press Ctrl + Shift + Esc to open the Task Manager.
Step 2. Find the Dropbox process in the list.
If Dropbox is listed under the Processes tab, select it and click End Task. If Dropbox is not listed or the sync task has already ended, click the desktop icon to restart Dropbox.
Solution 2: Clear the Dropbox cache
Step 1. Open File Explorer (Windows) or Finder (Mac), and navigate to the path: ~/Dropbox/.dropbox.cache. For Windows users, cache files are typically found in C:\Program Files\Dropbox. For Mac users, go to Finder, then select "Go to Folder..." and enter the path.
Step 2. Select all files in the cache folder and delete them.
