A family of Microsoft word processing software products for creating web, email, and print documents.
Your method doesn't work on my android tablet. I always get the message "you don't have permission to delete this file.
But there is one way that I've found that does work for me. I go to settings/apps and go to Word.
Under storage select clear data. That clears out all files you've saved or were sent there. Before I do this, I make backups onto my laptop of files I want to keep.
Kind of a inconvenient way to clear out word but it's the only method that works for me.
Thanks for your help.
