If synchronizing your files has been too difficult with any software so far, you should try the beta version of Easy2Sync for Files. The “New task” assistant has undergone a major rework to make it very easy to set up a synchronization task.
Especially sharing a folder can be difficult on a Windows PC, but it’s always necessary for a file synchronization. The new release makes this a lot easier by proving a wizard that helps you choose and share the right folder.
