Local data
Foxglove can load local data files for visualization.
Supported formats
| File extension | |
|---|---|
| ROS 1 | .bag |
| ROS 2 (legacy) | .db3 |
| ROS 2 (Iron onward) | .mcap |
| MCAP | .mcap |
| PX4 ULog | .ulg |
tip
Since legacy ROS 2 .db3 files do not contain their message definitions, we recommend first converting those into self-contained MCAP files before loading into Foxglove.
Getting started
To load local files for visualization, you can:
- Click "Open local file(s)…" in the dashboard or left hand menu
- Open or drag-and-drop the files from your OS file manager (desktop only)
note
When opening multiple files, Foxglove will merge the data into a single playback timeline.
You can only merge multiple files of the same format.
