bocvarbocdar File properties refer to all database fields associated with the file, including the familiar ones such as Artist, Album, Genre, but also including custom fields. These properties are saved in the library. Many of these fields can also be saved in the files themselves (referred to as 'tags'), depending on the format of the file.

For audio content, the mp3 (id3v1 and v2), ogg, wma, ape, and mpc can store properties. Only jpg files can store properties for images, and video or document files cannot store properties.

Some of those tags can be viewed in other programs, including Artist, Album, Name, Year, Genre, Comment and track #, whereas all tags can be viewed in Media Center.

For more information on which tags can be saved for use with other programs, please see

One of the advantages to saving the information in the file itself is that you can re-import that file into any library and still have access to all the information. However, it also increases the file size, especially when things such as cover art, lyrics and extensive notes are saved.

A good compromise is to save some tags in the file, and others in the library only. See Save File Properties in Disk Files for more information.

Custom Fields

Custom fields can be added in Tools->Options->Libraries & Folders->User Library Fields.

Custom fields can be of type string, integer, decimal, percentage, or semicolon delimited list. They cannot be of type "rating".

Importing the 'tag' information

By default, the import process fills in the library fields with the id3 tags in the file. We recommend using this default setting.

If you want to change the setting:

  • Go to Tools > Plug-in Manager > Input > MP3 Plug-in and select Configure
  • Check "Ignore ID3v2 tag during analysis". While this may speed up the import process, it will also limit the information retrieved from the file.

For images and video, Media Center will fill in the Album field with the year of the image or video (if the album field is otherwise empty). This puts a reasonable value there when importing directly from a digital camera.
