# Use Media Previews

Media previews let you inspect vault files without leaving Tolaria.

## Open A File

Select an image, PDF, media file, or unsupported file from a folder or file list. Tolaria opens supported files in the app and offers an external-open action for files that should use the system default app.

## All Notes Visibility

Open Settings to choose whether non-Markdown files appear in All Notes:

- PDFs.
- Images.
- Unsupported files.

Folder browsing still shows files in their folders even when a category is hidden from All Notes.

## Attachments

When you paste or drop an image into a note, Tolaria copies it into the vault and references the copied file from Markdown.

## Troubleshooting

If a preview does not render, open the file in the default app to confirm the file is valid, then check whether the file is inside the active vault and not blocked by operating-system permissions.
