Identification

• A file with a wmdb file extension is known as a Windows Media database file. The file extension is a marker for Windows Media Player, allowing it to quickly locate and access the file.
  
  

Location

• You are likely to find a wmdb file within the program folder for Windows Media Player.
  
  

Function

• Windows Media Player is able to perform a search of your entire hard drive in order to locate audio and video files that the program is able to play. The results of this search are saved in a wmdb file.
  
  

Benefits

• Wmdb files allow Windows Media Player to display all available files for you to select no matter where the file is on your computer. Additionally, when you want to play a particular file, the wmdb file tells the player where the file is so it can be played.
  
  

Considerations

• Wmdb files are not meant to be opened. Each time you add or delete a file, Windows Media Player will automatically save the changes with its next search.
