Files and previews

The Files tab is the project file cabinet. It is where you bring in source material, inspect what an agent made, and check the files that belong to a project. When you say “summarize the invoice I uploaded” or “make a CSV from these screenshots,” the Files tab is where that work becomes visible.

Browsing files

Open Files from a project. You can browse folders with the breadcrumb path at the top, open a folder by selecting it, or use Up to move back toward the project root.

The file list has two views: List for names, dates, and sizes, and Grid for a thumbnail-style view that is nicer for images. Lowkey remembers the view you chose. Sort by Name, Modified, or Size, then flip the arrow to reverse the order. Folders stay grouped ahead of files.

Use Filter when you know part of the filename. It searches within the folder you are currently viewing, so “receipt” narrows the current folder without pulling in matching files from everywhere else.

Adding and managing files

Drag files onto the Files tab to upload them. If your browser exposes folder drops, Lowkey keeps the folder paths and uploads the contents into matching folders. In an empty folder, you can also choose Upload files or Upload folder. Each upload appears in a small queue with progress, cancel, retry, and dismiss controls.

Use New folder to create a folder in the current location. Right-click a file or folder to open its menu. From there you can Open, Rename, Copy path, or Delete. Files also have Download and Duplicate. Select multiple items to show bulk Download and Delete; bulk download applies to files, not folders.

Previewing files

Select a file to preview it beside the file list. Lowkey can preview PDFs, images, Word documents, PowerPoint presentations, Excel workbooks, CSV and TSV files, email .eml files, HTML, code, Markdown, and JSONL. If a file type does not have a preview, Lowkey offers a download instead.

Images have zoom controls, reset, wheel zoom, double-click zoom, drag-to-pan when zoomed, and pinch gestures on touch screens. PDFs have page controls, zoom controls, reset, drag-to-pan when the page is larger than the view, and a PDF download button. CSV previews can switch between table and source; HTML previews can switch between rendered HTML and source; code and CSV previews include copy buttons. Excel previews are for inspection: they show sheet tabs and a bounded table, not a full spreadsheet editor.

Staying in control

Files are real project files. Delete asks for confirmation, and closing a preview does not change the file. If you only need to see something an agent is showing you while you keep chatting, use the focus pane instead of treating Files as a presentation area.
