So I did the Windows 10 upgrade from Windows 7, then did a reset. I opted to keep nothing and get rid of any partitions. All running well, but when I checked, I still have the old partions. As well as C drive there is the HP Recovery D Drive and HP Tools E drive.
E Drive is empty. D Drive has a folder in it with a russian doll sequence of folders - each folder opens to reveal another folder, and finally the file marked'AutoLogger-Diagtrack-Listener.etl.
Anyway I don't know what it is and I want to delete those partitions and expand the C drive. Will that delete this file and is it ok to delete it? And why is it there?!! I thought a full reset keeping nothing and losing partitions was the same as a clean install.
