## Best for

Square preview cards in a grid of up to 6 columns, a ring over each while sending and a tooltip retry on failure

## Agent notes

- `defaultFiles` points 2 of its 3 samples at /media/files placeholder paths; swap in the user's stored files
- `simulateUpload` fakes progress and fails about 1 in 10 files at the end; feed real upload events into `uploadFiles` instead

## When not to use

- Documents listed as rows with type and size columns: use [Table](https://reui.io/components/file-upload/c-file-upload-6.md) (`get_example("c-file-upload-6")`)

## Install

```bash
npx shadcn@latest add @reui/c-file-upload-9
```

## About Shadcn File Upload

### When to use

- Profile pictures and cover banners replaced by one pick or drop, with an instant local preview
- Multi file drop zones that check type, size and count, then list picks as thumbnails, cards or table rows
- Upload queues with per file progress and retry, and photo grids put in order by drag before saving

### When not to use

- Chips for files sent with a chat message, in the composer or the reply: use [Attachment](https://reui.io/components/attachment.md) (`get_component("attachment")`)
- A colored document icon labeled with its format, such as PDF or XLSX: use [File Type](https://reui.io/components/file-type.md) (`get_component("file-type")`)
- A meeting or booking form where an image drop is one field among many: use the [Schedule blocks](https://reui.io/blocks/application/schedule.md)

### Agent notes

- No example sends a picked `File` to a server; picks stay in React state until you add the upload request
