twislaandClaude Sonnet 5.5 b2bc556f6e Site: how-tos and the FAQ (phase 3)
Eight how-to recipes and a FAQ page with a list of its questions, from the
README, the milestone documents and the Apps' source. The guide templates
become generic (the parent section gives the eyebrow, title and pager).

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` |
## 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.
