File Explorer

Fresh includes a built-in file explorer.

Toggle Sidebar: Use Ctrl+B to show/hide the file explorer sidebar. When a nested file is active, toggling on expands the tree and reveals the file.
Focus: Use Ctrl+E to switch focus between the file explorer and editor.
Navigation: Use the arrow keys to move up and down the file tree.

Opening Files

Enter opens the selected file and focuses the editor.
Arrow Up/Down also opens the highlighted file in a preview tab automatically as you move — so you can scan files without leaving the keyboard.
Single-click opens a file in an ephemeral preview tab — the next single-click on another file replaces it instead of piling up tabs. Any real commitment — editing the file, pressing Enter, double-clicking, clicking the tab itself, or a layout action like splitting — promotes the preview to a permanent tab.
Double-click opens the file in a permanent tab and focuses the editor.

Preview tabs are enabled by default. Turn them off in the Settings UI if you prefer every click to open a permanent tab.

Ctrl+C / Ctrl+X / Ctrl+V — copy, cut, or paste the selection. Same-directory copy auto-appends copy / copy 2 etc. Same-directory cut is a no-op. Paste into a different directory with a name conflict prompts per-file: (o)verwrite, (O) all, (s)kip, (S) all, (c)ancel.
Cut-pending items are visually dimmed. Cancel a pending cut with Escape or by pasting back into the same directory.
Shift+Up / Shift+Down extend a multi-select range from the current anchor; all clipboard operations (and delete) act on the whole selection.
Buffers follow files — renaming or moving a file (via cut+paste) relocates any open buffers pointing at it; deleting a file closes its buffer. Renaming a directory relocates buffers for every file inside it.

The sidebar's width is configurable via file_explorer.width in settings. It accepts either form:

Dragging the divider preserves whichever form you configured — a sidebar set up as a percent stays a percent after you drag it.

The file explorer respects your .gitignore by default, and auto-reloads when .gitignore changes on disk.
A file is shown only if it isn't hidden by any active filter — so if a file is both a dotfile and gitignored, it takes enabling both toggles to see it.
Use Toggle Hidden Files and Toggle Gitignored Files from the command palette to flip either filter. Both settings persist to config across sessions.
