Opened my W10 PC today and my personal folder was gone, all 5Gb.

Searched my PC for the folder name and also for sub folders by name in case it was moved but no luck.

Luckily I do a daily backup and could restore it all.

The newest file in my personal folder backup was dated 27th June and the oldest "date deleted" file in my Recycle Bin is dated 5th June so clearly my personal folder did not pass through the bin.

Now I have broken my personal folder into several smaller ones to simplify backup and restore.

I have run a couple of virus checkers which did not identify any issues so I have no clue how to stop this happening again.

I backup to the cloud, do a daily clone to an external drive, copy my documents, music and photos folders each day to a different external drive and another continuous backup to the net. And I still worry I’m going to lose something.

Why? Because it’s happened to me before.
