I set my backups with “Copy with deleting other than source files” & “incremental backup”, so, all works OK but Comodo BU leave empty folder…for example:
I delete the folder in D:/mp3/iron maiden, comodo delete all files inside in E:/mp3/iron maiden but the folder remains.
I have found that I also have empty folders left behind when I chose that setting. Hope that someday C Backup will be updated. I still find it the most reliable and best backup that I have used.
