An App in the Launcher that runs the same commands as USB serial and the Debug Console, trusted like the first. It shows what the console prints while it is open, through a second ring of the console's that exists only meanwhile; Ctrl+b keeps only what follows your own commands. Tab completes a command's name from the firmware's help text, Fn with up and down recalls earlier lines, Alt with up and down scrolls back. `rm` asks first in the Shell, `rm -f` doesn't. Nothing is kept once the App is left. `screenshot [seconds]` saves the screen as a PNG in /screenshots on the card, now or after a pause: written a row at a time, indexed colour with RGB332 as the palette, in one stored deflate block. 487 host tests (11 new: the PNG writer, the Shell's log filter, Tab). Checked on the device over the Debug Console: commands, Tab, history, a screenshot fetched and decoded on the PC, rm with and without the question, a delayed screenshot of another screen. 12 KB of flash; 7 KB of heap while open. Decisions Q204 to Q212 in docs/milestones/S1.md. Safe Mode: #77. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT

Everything the firmware writes goes in a folder at the top of the card. Switch the Cardputer off, take the card out and read it in a computer; or look at the same folders in the [Storage App](/guide/storage/).

| What | Where | Kind of file |
|
|
|---|---|---|
|
|
| Notes | `/notes` | `.txt`, named after the first line |
|
|
| GNSS Tracks | `/gnss/tracks` | `.gpx`, named by date and time |
|
|
| LoRa captures | `/captures/lora` | `.pcap` |
|
|
| IRC logs | `/irc` | one text file per buffer and day |
|
|
| Wi-Fi scan logs | `/wifi/scans` | `<date>.csv` |
|
|
| Gemini Saved Pages | `/gemini/saved/<host>/…` | `.gmi` |
|
|
| Gemini bookmarks | `/gemini/bookmarks.gmi` | gemtext |
|
|
| Files saved from Gemini that are not text | `/gemini/downloads` | whatever they were |
|
|
| Update files | `/updates` | `.ota` |
|
|
| Screenshots (the Shell's `screenshot`) | `/screenshots` | `.png`, named by date and time |

## Rules worth knowing
|
|
|
|
- **Eject first.** A file being written (today's IRC log, a Track or a capture being recorded) is not complete until it stops. Stop it, or switch the device off, before you take the card out.
|
|
- **Notes are yours.** You can edit them on a computer and they show up on the device; the clean-up never offers them for deletion.
|
|
- **Don't rename the top-level folders.** The firmware looks for them by name.
|
|
- **Logs stop at 90% full,** so the remaining space is kept for captures. The [Storage App](/guide/storage/)'s Maintenance shows what is using the card and clears old logs and captures, after showing what it would free.
