*The MDataStore.db3 file is also used by Nokia Suite to store user data, such as: SMS, calendar entries and contact information. Therefore, users of Nokia Suite are advised to backup any user data before removing the .db3 file.
- Vista and 7 C:\Users\<user>\AppData\Local\Nokia\Nokia Data Store\DataBase\MDataStore.db3
- XP C:\Documents and Settings\<user>\Local Settings\Application Data\Nokia\Nokia Data Store\DataBase\MDataStore.db3
Both of these locations are in hidden folders. So, to view them users will need to:
Open Windows Explorer > Tools > Folder Options > View > Show Hidden Files and Folders
Once Nokia Music Player is opened again the MDataStore.db3 file will be rewritten to this folder.
This FAQ applies to Nokia Lumia phones with Windows Phone 8, and a computer running on Windows 7, Vista or Windows 8. If you have Windows XP use the search field on this page to find this related FAQ: What should I do if my Nokia Lumia phone is not recognized by a computer running Windows XP?
Start by disconnecting your phone and other USB devices connected to your PC. Exit the PC software, such as Nokia Suite, Zune and Windows Media Player, which can establish a USB connection at the background. Use Ctrl+Alt+Del to see and manage processes that are running on your PC.
Check that you have latest updates installed on your PC
Here are two options to follow (ensure that Administrative rights are available):
Check your USB connection
Make sure that you are using the USB cable which was included with your phone. You may also try another port on the computer, but do not use a USB hub or the ports located on the front of your computer. Most versions of Windows (excluding Windows RT) allow you to connect to your Lumia with Windows Phone 8 by using Windows Explorer, which you can use to validate that you have an active connection.
Check and update your device driver
Confirm that your PC is able to communicate with Windows Update service through firewall(s).
You can also use the Windows Phone app, which is a free app for PC and Apple Mac. With the app, you can sync media content between your computer and your phone. This includes the music, pictures, videos, movies, ringtones, and podcasts on your computer that you want to copy to your phone. Windows 8 installs the app automatically. With Windows 7, you can download it from www.windowsphone.com. If you have a Mac, to download and install the Windows Phone app, go to the Mac App Store.
