# Portfolios and folders

> Folders for your content, including a Main portfolio you never have to create.

A portfolio is a folder. It holds blueprints, standalone diagrams, links and
notes, and it can hold other portfolios.

## Main

Every workspace has a **Main** portfolio, created automatically. Anything you
make without choosing a home lands there. It cannot be deleted.

## One home each

An item is in exactly one portfolio at a time. Filing is a move, not a copy.

> [!TIP]
> If you want the same blueprint to appear in two places, link to it from a
> note or embed it. Duplicating it means maintaining two.

## Ownership

A portfolio is owned by you, a team, or an organisation, the same three
owners as everything else. A portfolio's owner and its contents' owner are
independent: filing an organisation blueprint into a personal portfolio does
not make it yours.

## Nesting

Subfolders go as deep as you want. Two or three levels is usually enough.

## Links and notes

A portfolio can also hold plain links and short notes, so a folder can keep
the context around a set of blueprints: the ticket, the decision record, the
"read this first".
