<application>dconf</application> uses several database files in GVDB binary format, one database per file.
A dconf profile consists of a single file, in plain text format, which contains a list of database files in GVDB format.
All dconf profiles are stored in the <filenameclass='directory'>/etc/dconf/profile</filename> folder.
In most systems, there is no dconf profile file since they only use the default database, user.db which is stored in ~/.config/dconf/user. In such case, there is no system-wide setting, i.e. users just have their own settings.
Example of content for the user profile (/etc/dconf/profile/user file):
