4.2. Database
4.2.1. Introduction
This chapter describes the Rockbox music database system.
Using the information
contained in the tags (ID3v1, ID3v2, Vorbis Comments, Apev2, etc.) in your audio
files, Rockbox builds and maintains a database of the music files on your player and
allows you to browse them by Artist, Album, Genre, Song Name, etc. The criteria the
database uses to sort the songs can be completely customised. More information on how
to achieve this can be found on the Rockbox website at
4.2.2. Initializing the Database
The first time you use the database, Rockbox will scan your disk for audio files. This can
take quite a while depending on the number of files on your player. This scan happens
in the background, so you can choose to return to the Main Menu and continue to listen
to music. If you shut down your player, the scan will continue next time you turn it on.
After the scan is finished you may be prompted to restart your player before you can
use the database.
Ignoring Directories During Database Initialization
You may have directories on your player whose contents should not be added to the
database. Placing a file named
database.ignore
in a directory will exclude the files in
that directory and all its subdirectories from scanning their tags and adding them to the
database. This will speed up the database initialization.
If a subdirectory of an ‘ignored’ directory should still be scanned, place a file named
database.unignore
in it.
The files in that directory and its subdirectories will be
scanned and added to the database.
4.2.3. The Database Menu
Load To RAM
The database can either be kept on hard disk (to save memory), or
loaded into RAM (for fast browsing). Setting this to
Yes
loads the database to
RAM, allowing faster browsing and searching. Setting this option to
No
keeps
the database on the hard disk, meaning slower browsing but it does not use extra
RAM and saves some battery on boot up.
Note:
If you browse your music frequently using the database, you should load
b
to RAM, as this will reduce the overall battery consumption because the disk will
not need to spin on each search.
Auto Update
If
Auto update
is set to
on
, each time the player boots, the database
will automatically be updated.
