The Database Menu - Samsung YH-920 Manual

Chapter 4. Browsing and playing
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
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.
Initialize Now You can force Rockbox to rescan your disk for tagged files by using the
Initialize Now function in the Database Menu.
Warning: Initialize Now removes all database files (removing runtimedb data
also) and rebuilds the database from scratch.
Update Now Update now causes the database to detect new and deleted files
Note: Unlike the Auto Update function, Update Now will update the database
regardless of whether the Directory Cache is enabled. Thus, an update using
Update now may take a long time.
Unlike Initialize Now, the Update Now function does not remove runtime
database information.
Gather Runtime Data When enabled, rockbox will record how often and how long a
track is being played, when it was last played and its rating. This information can
be displayed in the WPS and is used in the database browser to, for example, show
the most played, unplayed and most recently played tracks.
Export Modifications This allows for the runtime data to be exported to the file
/.rockbox/database_changelog.txt, which backs up the runtime data in ASCII
format. This is needed when database structures change, because new code cannot
read old database code. But, all modifications exported to ASCII format should
be readable by all database versions.
