`w` in the Storage App starts a small HTTP server and shows its address,
as a QR code and in letters, with a six-digit code. A browser on the same
network that has typed the code can list, download, upload, make folders
and delete, under the Storage App's rules. The server runs only while that
screen is open. Nothing is encrypted, and the screen says so.

Uploads are streamed to the card under a temporary name and renamed when
whole. Every access to the card is handed to the storage task, 8 KB at a
time, from the server's own task.

A copy runs in the background of the card (about 400 KB a second) in short turns, so Logs and Captures keep being written; it shows its progress, Back cancels it and takes back what was copied, and each file's size is checked afterwards. Three things can't be changed: the top-level folders the firmware keeps its files in (what's inside them can), `/gemini/cache`, and any file being written right now (today's IRC Logs, a Track or a Capture being recorded). The App says why when it refuses. A folder with more than 256 entries shows the first 256 by name and says so.
**`w` shares the card with a browser on the same network** (issue #88): a small HTTP server and one page, for a phone with nothing to install. The screen shows the address as a QR code and a six-digit code, new each time; whoever has typed it can list, download, upload (streamed to the card under a temporary name), make folders and delete, under the Storage App's rules. It runs only while that screen is open, takes one request at a time, moves about 200 KB a second, and is not encrypted. It costs 57 KB of flash, and 13 KB of memory while it is on.
Enter on a file opens it by type; Tab switches to the same file as a hex dump or as text:
- **Text** (`.txt`, `.log`, `.gmi`, `.csv`, and anything that looks like text): only the screen's worth is read from the card, so a file of any size opens at once. Logs open at the end. Up and Down move a line, Left and Right a page, `t` and `b` go to the top and the end, `e` edits it, whatever its size (see Notes).
