+When running a workflow in chat mode, you can attach up to **10 files** to your message.
+**To attach files:**
+
+1. In the chat input area, attach files using any of these methods:
+   - Click the **paperclip** icon in the input toolbar to open a file picker
+   - Drag and drop files directly into the chat window
+2. Each uploaded file appears as a chip with options to preview, download, or remove it.
+3. Send your message to start the workflow execution.

+
+**Supported file types and limits:**
+
+| Parameter     | Value                               |
+| ------------- | ----------------------------------- |
+| Max files     | 10 per execution                    |
+| Max file size | 100 MB per file                     |
+| File formats  | CSV, PDF, JPEG, JPG, PNG, GIF, PPTX |
+
+**How files are available in workflow steps:**
+
+Each attached file is appended to the task description of every state:
+
+```
+File attached: filename.ext
+```
+
+The full list of file names is also accessible via the `{{file_names}}` context variable in YAML task templates or tool arguments.
+
+:::tip Referencing a specific file
+Mention a file by name (e.g., `@report.pdf`) to direct a step to focus on that specific file rather than processing all attached files.

 ### Chat History
 
 Workflow chat history works the same way as with regular assistants. You can always review your workflow conversations in the Chats tab that started in a chat mode, where you'll find:

-1. Create a workflow with a user prompt step that requires file input
-2. Configure the state with `interrupt_before: true`
-3. In the task description, specify that file upload is expected
-4. Add appropriate handling for the uploaded file in subsequent states
+1. Open the workflow and click **Start Chat**.
+2. In the chat input area, click the **paperclip** icon to open a file picker, or drag and drop files into the window.

-5. Execute
+## How to Configure File Input in YAML
+
+To design a workflow that explicitly waits for file input from the user, configure a state with
+`interrupt_before: true`. This pauses execution before the state runs, allowing the user to
+provide files and additional input:
+
+```yaml
+states:
+  - id: await-files
+    assistant_id: file-processor
+    interrupt_before: true
+    task: |
+      Process the attached files.
+      Files: {{file_names}}
+```

 # Can I use different types of files in the same workflow execution?
 
-Currently, only one file can be attached as input while executing a workflow. Ensure the file is appropriate for the workflow's context to provide accurate and relevant results.
+Yes. When running a workflow in **chat mode** (via the **Start Chat** button), you can attach up to
+**10 files** of different types in a single execution. Supported formats are CSV, PDF, JPEG, JPG,

+# How are attached files accessible in workflow steps?
+
+When you attach files to a workflow execution in chat mode, each step in the workflow receives
+the files in two ways:
+
+1. **Task description**: Each attached file is appended to the task description as
+   `File attached: filename.ext`, so the AI assistant in that step is aware of all files.
+
+2. **Context variable**: The full list of file names is available as `{{file_names}}` in the
+   context store. You can reference this in YAML task templates or tool arguments:
+
+```yaml
+states:
+  - id: process-files
+    assistant_id: analyzer
+    task: |
+      Analyze the following files: {{file_names}}
+      Provide a summary for each file.
+```
+
+Files are included in every step automatically — no additional YAML configuration is required.
