 Arrow keys move through the files, and Space opens the full-screen quick look. Selection works like Finder or Explorer (Ctrl, Shift, keyboard).
 
+### Browsing by folder
+
+The third view button (the folder icon, next to grid and list) turns the explorer into a file manager over what was found. The center shows **one folder at a time**: its subfolders first, each with how many files and how much space it holds counting everything below it, then the files directly inside. A breadcrumb at the top (`Root › Documents › Project`) goes back up; double-click or Enter opens a folder, Backspace or Alt+↑ goes up, and clicking a folder in the sidebar tree jumps to it. Files found only by signature, which have no known folder, sit in **By signature** at the root. Filters (type, date, confidence…) still apply and change the counts.
+
+To recover, tick folders and files with their boxes; the selection survives navigation. Ticking a folder takes **everything inside it**, at any depth, even what the active filters hide. Unticking a subfolder or a file inside a ticked folder leaves the folder half-ticked and keeps that item out. The bottom bar shows the exact total, and **Recover selection** recreates each ticked folder in the destination **from itself down**: recovering `Documents/Clients/Project` writes `Project/...` with all its subfolders. Files ticked on their own go to the root of the destination, and two ticked folders with the same name become `Project` and `Project (2)`. The manifest with MD5, SHA-1 and SHA-256 is written as always.
+
+Only folders that hold at least one recovered file appear: Guará knows folders through the paths of the files it finds.

 ## Themes
 
 The switch at the bottom of the sidebar offers **Auto** (follows the system), **Light** and **Dark**. The choice is saved.
