Type folders

A folder at the root that takes everything with one of its extensions, instead of the dated folder.

Switch on Installers and every .dmg, .pkg, .mpkg, .iso and .app lands in ~/Downloads/Installers/, whatever day it arrived on:

~/Downloads/
├── Installers/
│   ├── Figma.dmg
│   └── node.pkg
├── 2026-08-18/
│   └── invoice.pdf
└── report.pdf          ← downloaded today, stays put
The Type folders pane: each folder with its extensions and a switch, three of them switched on and the rest waiting

What ships, and what is on

The app comes with Installers, Archives, Images, Documents, Spreadsheets, Presentations, Audio, Video and Fonts, all switched off — nothing changes until you turn one on.

Any of them can be renamed or re-scoped, and Add a folder of your own takes a name and a list of extensions (torrent, magnet) for anything the list does not cover.

Catch Up

Switching a folder on only steers what arrives next — files already tucked into a dated folder stay there. Catch Up… brings them into line: it looks through the dated folders, shows you everything the rules now claim grouped by where it would go, and moves only what you leave checked.

A dated folder left empty by that goes to the Trash. Folders you made yourself are never opened, and a name already taken in the type folder is never overwritten — report.pdf arrives as report-1.pdf.

Where, not when

A type folder decides where something goes, not when. A .dmg downloaded today still sits loose in the root until it is older than the Leave loose in the root window — it just goes to Installers/ rather than to a dated folder when its time comes.

Three more things follow from that:
