.NOMEDIA File Extension
File TypeAndroid No Media File
File stored on an Android mobile device, or on an external storage card connected to an Android device; marks its enclosing folder as having no multimedia data so that the folder should not be scanned and indexed by multimedia players; has no filename prefix and is named .nomedia.
The use of NOMEDIA files helps boost performance by excluding folders that do not need to be scanned. For example, a folder that has thousands of songs or images can be excluded. Many Android audio and video players as well as image browsers (Gallery, MP3 Player, Video Player, etc.) recognize NOMEDIA files.
NOTE: NOMEDIA files can be managed by utilities such as StudioKUMA .nomedia Manager or Nomedia.
