Empty folders and files does not sync

[ccarderr]

I have problem with empty files and folders, they just don't sync. Also emptying file will delete it on other computers.
Don't know if it's on purpose, if so then option to change this behavior would be great.

Example on two computers [A] and [B].
Creating empty folder on [A] will not sync it to [B].
Creating empty text file on [A] will not sync it to [B].
Modifying the file (adding text) on [A] will sync that file to [B].
Modifying the file (deleting all text) on [A] will delete file on [B].
