## Start from an empty room

When a room has nothing on its canvas, a card titled **Start your first review** appears in the middle, with the line "Review videos, images, and documents together."

### Add your first files

1. Drag files from your computer onto the area that says **Drop files here to begin**, or click **Upload asset** and pick files.
2. You can add several files at once. Supported types are videos (MP4, MOV, WebM), images (PNG, JPG, GIF, SVG) and PDFs.
3. The files appear on the canvas and the card goes away.

### Other ways to start

Below the upload area are three shortcuts:
- **Invite others**: invite people to this room (see [invite-people](https://www.pactto.com/help/invite-people.md)).
- **Create doc**: adds a collaborative document to the canvas.
- **Share your screen**: starts sharing your screen (see [share-screen](https://www.pactto.com/help/share-your-screen.md)).

You can also use the toolbar at the bottom at any time (see [canvas-toolbar](https://www.pactto.com/help/canvas-toolbar.md)).

### If a file is not accepted

- "This file type isn't supported yet." The file is not one of the supported types listed above.
- "File is too large. Maximum size is 5 GB." Each file can be up to 5 GB.
- When you drop several files and some are not supported, the others are still added and a message says how many could not be added.

Good to know:
- The card comes back whenever the canvas is empty again, for example if you delete everything.
- The card is not shown on phones (screens under 640 pixels wide), while someone is sharing their screen, or in conversation mode.

- [Where do new files appear on the canvas, and at what size?](https://www.pactto.com/help/asset-placement-and-size.md): New images and videos are placed in a free spot near the middle of your view without covering other items, shrunk to fit within 800 by 480 pixels if they are larger, and the view moves to show them.
