Losing your carefully organised Chrome bookmark folders can be a nightmare—especially when Chrome Sync or an accidental deletion wipes out your saved folders.
The method works by temporarily stopping Chrome Sync from overwriting your changes, restoring the backup file as your active bookmarks file, and then copying individual folders back into your restored bookmarks once Chrome has updated.
The key steps for both operating systems are: Disconnect from the Internet, Quit Chrome Completely, Access Your Chrome Profile Folder, Replace the Bookmarks File, Reopen Chrome Offline, Recover Each Folder.
By following these step-by-step instructions on macOS and Windows, you can manually restore deleted Chrome bookmark folders, even if Chrome Sync initially overwrites your restored file.
