"These Files Failed To Backup" - WD Easystore

As the title says, when I backup my PC with the WD Easystore portable Backup, the easystore software shows numerous files that failed to backup. The files are not very large ranging from 1.5-5.0 kbs and they have no file extensions so I have no idea what these files are. I’m not sure if this is useless stuff on my PC or if it’s something I really need to backup. I’m unable to copy/paste the file names in the viewing window of the software which is preventing me from searching for further info. Hopefully someone here can help me with this.
Thank you,
Ron

I forgot to mention, my PC is an old Acer Aspire x1300 running windows 7.

While searching about this problem I came across this thread (Files Failed to Backup) which sounds like my problem but there was no answer or problem solved in that thread.
Thanks,
