Summary
Attachments keep briefs, mockups and reference files on the task they belong to. Asana lets you upload a file or pull one from a connected cloud source, so the whole team works from the same document.
Step-by-step guide
Step 1
Open the task
Open your project in List view, such as Work requests. Hover over the task row and click the arrow beside the task name. The task details pane opens on the right with the task's fields.
Step 2
Find Add attachment
Scroll down in the details pane to the Attachments section, below Subtasks. Select the plus button labeled Add attachment next to the heading.
Step 3
Pick a source
The Attach knowledge dialog opens. On the left, Upload is selected by default, and you can switch to a cloud source such as Google Drive. Choose the source where your file lives.
Step 4
Choose a file to upload
With Upload selected, click Choose a file to upload to browse your computer and select the file. Your computer's file picker handles the selection, and the file then attaches to the task.
Why this matters
You are handing a task to a teammate and the brief lives in a separate file. Attaching it directly to the task means they open one place and find the work and its reference material together, with no hunting through chat.
