GNU Radio keeps block preferences, audio device choices and Companion cache in a config tree on Linux. Path and backup routine.
Last updated
GNU Radio separates preferences from signal work. Block paths, audio choices and Companion layouts live in a config tree in home. Flowgraphs live wherever saves put them.
That split keeps the config portable across machines with matching block installs. Copy the tree with Companion quit and the environment returns. Missing blocks after restore point to installs, not paths.
Where GNU Radio stores this, by platform
~/.config/gnuradio
Block preferences, audio choices and Companion cache. Back up with Companion quit. Flowgraphs stay outside this tree in working folders with .grc extensions.
Frequently asked questions
How do I move GNU Radio settings?
Copy the gnuradio config tree with Companion quit, especially grc.conf and the block cache. Preferences and window layouts travel together. Flowgraphs themselves stay in working folders, so include those for full moves.
Where are my flowgraphs?
In working folders wherever saves put them, commonly Documents with .grc extensions. The config tree only holds preferences and cache. Check recent files inside Companion for true flowgraph paths.
