The tree and the list

The sidebar holds every root you added — local folders and cloud buckets in one tree. The pane beside it lists whatever is selected.

The columns

Column	What it says
Name	with the icon of the format
Size	the object's size; a folder shows Σ until you click it
On disk	how much of a cloud object is on this machine: its cached copy
Modified	the provider's own timestamp
Cost/mo	what keeping this object at its storage class costs per month, for cloud rows
Class	the storage class, when the folder holds more than one
Note	the one thing worth knowing about the bill: days left of a minimum storage duration, or a small object billed at the class's minimum size
Activity	a sparkline of how this object's size has moved over the listings the app remembers

A column with nothing to say in this folder is left out: a local folder has no on-disk, cost, class or note column.

Σ counts a folder: click it, and every file under it is added up in one walk — the cell then says the size, and its tooltip how many files in how many folders. A walk stops at 20,000 files and marks the size with >. Click again to count again.

A cloud folder adds a cost line at its foot — what the folder, or the one object you picked, costs a month, its class and region — with Optimize beside it: see optimize. Prices need the bucket's region and class; those are asked of the provider once a session and kept.

The … menu's Information shows what the app knows of an object: its kind, which reader opens it, the views it has, its size and date.

The grid

The Grid icon in the toolbar, beside the list icon, shows a folder as tiles instead of rows; Icons shows the pictures alone, filling the tiles. Each tile is a preview of what the object is:

Object	Its tile
an image or a texture	the picture
a PDF	its first page
a slide deck	its first slide
a drawing or a diagram	the drawing
a Markdown, Word or Jupyter document	the start of its page
a table	its row and column count, and first rows
a text file	its first lines
an archive, an ebook, a disk image, a database	the names at its top
anything else	the icon of its format

Tiles come in five sizes, 64 to 256 pixels; the magnifier icons step between them. Two arrows sort by name, up or down.

Drag a tile to put it where you want it. That layout is kept for the folder, until you sort it again. ⌘Z undoes, as in the list, and Esc clears the selection.

Reading a folder again

A cloud listing is kept, and shown at once the next time you step into that prefix. Younger than eight hours, it stands as it is; older, it is shown while the provider is asked again in the background. Refresh in the … menu asks the provider now, past that.

Hidden and deleted rows

Two toggles in the … menu decide what the list shows beyond the obvious:

• Hidden — dot-files and __MACOSX. They are hidden until you turn this on.
• Deleted — a name this folder had before and does not have now, struck through. Nothing is marked deleted until a folder that knew the name lists it again without it, so the mark means "it went", not "it was never here".

Keyboard

Arrow keys walk every row, and ⇧ with them extends the selection; → enters a folder and ← steps out; Enter opens what is selected. PageUp PageDown move a screenful, Home End go to the ends, and ⌘A selects all. The full list is on keyboard shortcuts.

Next: where the storage went.
