I use Microsoft Word for Windows in the office and am quite comfortable with it. When finished with a document, I close the file. Our rule is not to save our documents as they are no longer needed after printing.
Access is denied.
Yet next morning that file will delete. It happens regularly. When you do this, text from your document is moved to the Clipboard. This is the colorful name given to a temporary area in memory where data can be stored and even viewed. That data still points to your document and will not let the computer delete it until the link to the clipboard is severed.
