You can activate the Database Storage for Audio Files (com.glide.db_audio)
Right-click the plugin name on the list and select
If the plugin depends on other plugins, these plugins are listed along with
their activation status.
If available, select the Load demo data check box.
Some plugins include demo data—sample records that are designed to illustrate
plugin features for common use cases. Loading demo data is a good policy
when you first activate the plugin on a development or test instance. You
can load demo data after the plugin is activated by repeating this process
and selecting the check box.
