Thank you for your time. I had routine backups of items checked (documents, pictures, music, etc) in the Back On Track program from NXT 4 that I could not see on the backup media used when I installed NXT 6 with Back On Track. Also, I tried a routine backup in NXT 6 that came out mostly empty, files missing as in the Desktop or Documents folders. I am working with a new computer and decided to just delete NXT 6 and go back to NXT 4 and now all is fine. I can do the backups with all the files present in them and see older backups. I just got fed up with NXT 6 and got a refund. Both versions were Pro and I am satisfied with NXT 4. I hope this information helps. Incidentally, I have an SSD in my new computer and when I plug in my 1 Tb USB backup drive, which is probably a form of SSD, Back On Track sees it as both another hard drive and a removable drive. Could your NXT 6 see NXT 4 backups and did it perform complete My Data backups with all files present? Also I never did a complete system backup (Entire Computer), just My Data backups. All work is on the latest Windows 10 Home versions.
