Delete some of the files on My Cloud EX2

My Cloud EX2 is set for continuous back up which is what I want and am happy with. Recently I have undertaken some work for a friend on my computer which is now completed. As expected it backed this work up showing a % rise in the used sector. I no longer need to keep this work nor its back up so have deleted it from my computer. Is there any way in which I can remove it from MY Cloud in so doing reducing the % used. Thank you for any help or comments with regard to this issue.

WD SmartWare is a backup software. As such, it’s designed to keep files expecting for them not to be erased. You can manually navigate your WD My Cloud EX2 and delete unwanted files from the WD SmartWare backup folder. However, this may cause for WD SmartWare to lose track of the current backup and start over.

If you would prefer for your files to be removed from your unit when they are removed from your system then a synchronization software is what you need as opposed to a backup software. WD Sync was designed for such purpose.

Thank you for getting back to me and your reply. I must admit I had not thought about it along those lines - but common sense states I should have. I will be leaving things as they are. Once again many thanks.
