Sync Any Folder
First, press Win+R, type cmd, and click OK while holding Shift+Ctrl to open a command prompt with elevated privileges. (If done correctly, you will see a UAC prompt and the word "Administrator" in the title bar.)
Press Win+E to open File Explorer, right-click the OneDrive folder, click Properties, and copy the path from the address bar.
Use the following command to link the folder you want to the OneDrive folder, for example:
mklink /D "{OneDrive文件夹路径}\{OneDrive文件夹中的相对路径}" "{你要链接的文件夹路径}"Replace {} and the content inside it with your own path.
This uses the Windows symbolic link feature, which lets you link a folder to another location while it still appears in File Explorer as the original folder.
You can link a folder to another location without moving it, for example adding it to the OneDrive folder for easier syncing.
Type mklink /? in the command prompt to see more usage options.
