For using on another pc (I work in audio production), I recently transferred over 500 albums of music into an external drive. I get the following error message when I try to move, play, transfer, copy or ANYTHING with any file or folder: Cannot access the file with Windows Media Player. The file might be in use, you might not have access to the computer where the file is stored, or your proxy setting.
Cannot transfer into external drive
Have you checked the format in which you are playing these files? You could check the file format.
Another reason that it might not be playing is the Windows media player might be corrupted. You could use the following steps to fix:
1.Shut the media player down
2. Stop the media sharing service. Go to Start->Control Panel->All Control Panel Items->Administrative Tools->Services. Right-click on the “Windows Media Player Network Sharing Service” and select Stop.
3. Navigate to “c:Users”your username”AppDataLocalMicrosoftMedia Player. Now delete the files named CurrentDatabase_***.wmdb and LocalMLS_*.wmdb.
4. commence the media Sharing service
5. Restart the player.
If this method does not work you have to program the player so that it recognizes the particular folders in the drive that has the files. You will need to ensure that your device is plugged in and then click on F3.
Then
Click on advanced options
Click Add button (below the list of folders). Then just follow the instructions and set according to your preferences
