Directory Cache. Rockbox has the ability to cache the contents of your drive in RAM.
The Directory Cache takes a small amount of memory away from Rockbox
that would otherwise be used to buffer music, but it speeds up navigation in the
file browser by eliminating the slight pause between the time a navigation button
is pressed and the time Rockbox responds. Turning this setting on activates the
directory cache, and turning it off deactivates the directory cache.
Note: The first time you enable the directory cache, Rockbox will request a reboot
b
of the player and upon restarting take a few minutes to scan the drive. After this,
the directory cache will work in the background.
8.5.4. Idle Poweroff
Rockbox can be configured to turn off power after the unit has been idle for a defined
number of minutes. The player is idle when playback is stopped or paused. It is not idle
while the USB or charger is connected , or while recording. Settings are either Off or
1 to 10 minutes in 1 minute steps. Then 15, 30, 45 or 60 minutes are available.
8.5.5. Limits
This sub menu relates to limits in the Rockbox operating system.
Max Entries in File Browser. This setting controls the limit on the number of files that
you can see in any particular directory in the file browser. You can configure the
size to be between 50 and 10,000 files in steps of 50. The default is 400. Higher
values will shorten the music buffer, so you should increase this setting only if you
have directories with a large number of files.
Max Playlist Size. This setting controls the maximum size of a playlist. The playlist
size can be between 1,000 and 32,000 files, in steps of 1,000 (default is 10,000).
Higher values will shorten the music buffer, so you should increase this setting only
if you have very large playlists.
Note: You will need to restart your player for changes to these options to take effect.

This setting controls the amount of time the button lights shine after a button press. If
set to Off, the LEDs will not light when a button is pressed. If set to On, the lights
will never shut off. If set to a time (1 to 120 seconds), the buttons will stay lit for that
amount of time after a button press.
