The header holds the app name and search. Below it, a sticky toolbar holds the breadcrumb, then Home / Up navigation plus every action: view toggle, multi-select, upload, paste, new folder, bookmarks.
The home screen shows a grid of storage locations (admin accounts only — see Security & Permissions) and your saved bookmarks.
Toggle with the view icon in the toolbar. Your choice is saved per-user on the server and restored next time you log in.
Right-click (or long-press) a file for a context menu with Copy, Cut, Rename, Delete, Download. Copy/Cut also work with Ctrl+C / Ctrl+X, Paste with Ctrl+V. A badge on the Paste button shows how many items are queued; cut items dim until pasted. Folder copies are recursive.
Toggle select mode to get checkboxes on every entry, for bulk delete.
Star a folder to bookmark it — bookmarks show in the sidebar and on the home screen, and are stored per-user on the server (not in browser storage), so they follow you to any device.
The toolbar search box filters the current folder's contents live.
