Add and Preview Files

The File extension keeps source material beside the documents, boards, and drawings that use it.

Add files

1. Make sure File is enabled in the workspace’s extensions.
2. Select Add file in the workspace tree.
3. Choose File.
4. Select one or more files from your device.

Lunaris previews common images, PDFs, plain text, Markdown, CSV, JSON, XML, DOCX, PPTX, and XLSX files.

Preview and download

Select an uploaded file in the workspace tree to preview it. Preview controls depend on the file type: images and PDFs are displayed visually, while supported text and office files are rendered in a readable view.

If a format cannot be previewed, the file still remains in the workspace. Open its More menu and choose Download to save a copy to your device.

Files in a cloud workspace upload and sync like other workspace content. Open important files while online before relying on them offline; a file that has not yet downloaded to this browser may need a connection before it can be previewed.
