Win 10 C:\Users\kxxxxxx\AppData\Local\Packages\

Hi,

This directory

C:\Users\karl\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Files\S0\12

appears to be a massive security breach!

A copy of almost every file that I have worked on is stored in this directory.

Previous posts have indicated that this directory/data can not be safely be deleted.

It is ALL my personal data, several hundred files.

Why is it hidden here and why should I not delete it?

How can I stop it being saved here?

Karl.
