Start with the file

Section titled “Start with the file”

Eidos File is an open, SQLite-backed format for structured data. A .eidos file stores tables, typed fields, records, and saved views. You can open this file in the Web Editor, edit it with the CLI, or embed it in your applications.

Eidos Lite is a desktop application for local folders. That folder is your Space. Lite keeps .eidos files alongside Markdown notes and attachments. Lite includes local history and optional Sync. All local files remain usable offline without an account.

One Space. Ordinary files.

Inside books.eidos, the Books table has fields such as Title and Status. Each record represents a book. The Reading view saves its filter and layout.

When you move the data, include its referenced local files.
