"Quicken cannot open the data file because it is in use by some other application"

When I try to open my Quicken (.QDF) data file by launching Quicken 2013, I get an error message that reads, "Quicken cannot open the data file because it is in use by some other application. Please close that application and try again." However, I have NO OTHER Applications running. What is the problem, and what can I do? This happened after I had had a manual backup to external drive not complete successfully.

It's not a Quicken problem.

Some other software on your computer is using your Quicken file. You need to find out what software that is and either stop running it, or control when/whether it accesses your Quicken file(s).

If you don't already have any clues (automatic backup application, for example?), I believe there are quite a few free apps around that can do the trick; Google for them. 

Here's one I think will work:

People come to Quicken Community for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

  1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
  2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
  3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
  4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
  5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
