The files that block the moving of the partition were there right from the get-go. I managed to create D and E, but C had this annoying limit on the reduction.
I can see the files, but can't delete them cos they're "in use".
Even as a retired person, I'm feeling stressed out about the time I'm wasting. Up until nearly 5am talking to T-Mobile about the daft phone I've got. Getting to grips with Android and the like is exceeding the time I'll spend on the phone if I live to be 100.
