# Download All Tabs

A tiny Chrome (Manifest V3) extension that downloads the **actual files** open
across the tabs of the current window into a single folder inside Downloads.

Built for the case where a window is full of direct file links — e.g. a pile of
lecture PDFs on Moodle — and you want them all saved locally in one click,
without saving the ordinary web pages mixed in.

## How it works

1. Click the toolbar icon. The popup scans the **current window** only.
2. Type a **folder name** (created under your Downloads directory; defaults to a
   dated name like `tabs-2026-06-03`).
3. Tick the **file types** to grab. Each distinct extension found in the window
   is listed with a count (e.g. `PDF — 12 tabs`). Real file types are
   pre-selected; ordinary web pages are grouped under "Web pages" and left
   unticked so they're skipped.
4. Hit **Download selected**. Each matching tab is saved into
   `Downloads/<folder>/`, keeping its original filename (name collisions are
   auto-numbered).

Downloads go through Chrome's own download manager, so they reuse your existing
session cookies — authenticated files behind a login (like Moodle) download just
fine, which a `fetch()` from the extension could not do because of CORS.

Example: a tab at

```
https://moodle.telt.unsw.edu.au/pluginfile.php/15056959/mod_resource/content/4/LECTURE%202%20T3%2024%20FINAL.pdf
```

is detected as a **PDF** and saved as `LECTURE 2 T3 24 FINAL.pdf`.

## Install (unpacked)

1. Open `chrome://extensions`.
2. Enable **Developer mode** (top-right).
3. Click **Load unpacked** and select this folder.
4. Pin the extension, open a window full of files, and click it.
