Clearing the media database

Jolla Care -

Sailfish OS has a worker called Tracker. Tracker harvests all media/document folders in Sailfish device and in the memory card (if any), creating a registry of files found. We call this registry by the name of media database in this article.

Sailfish media database contains the locations of music files, pictures, videos and documents.


1. Sailfish Utilities

It may happen that the database gets corrupted. Then it is possible to refresh it by using Sailfish Utilities.The device should be restarted after this. It may take a couple of minutes before Tracker has re-created the database.

2. Command line

Should the database be badly corrupted then it may be necessary to go to the command line (Terminal app) and reset the database there. Guidance for Developer mode. Note that those commands do not erase any media files - they only clear the registry.


 In terminal type

tracker reset -e

...or even

tracker reset -r



tracker reset [OPTION...]
Help Options: -h, --help Show help options

Application Options:

-r, --hard Kill all Tracker processes and remove all databases
-e, --soft Same as --hard but the backup & journal are restored after restart
-y, --yes Skip interactive verification for reset.
-c, --config Remove all configuration files so they are re-generated
on next start
-f, --file=FILE
Erase indexed information about a file, works recursively for directories.

3. Printout example
