# Provide a file as an automation parameter

> Automation parameters · Revit examples

## Overview

An attachment parameter gives the automation an explicit file input, such as a CSV sheet register. It can specify allowed extensions and a maximum file size.

Studio exposes Choose file or Replace file and reports unsupported types, oversized files or a read failure. This parameter belongs to the automation form and is separate from attaching a general reference to a chat.

## In Ideatura

1. Read the accepted file types and size limit.
2. Choose the intended file.
3. Check its identity and any validation message.
4. Run only after the file has loaded successfully.

## Check the result

The automation receives the intended file in an accepted format.
