Sometimes a customer needs a one-off file unique to their order — a customized PDF with their name, a personalized illustration, a contract with their details. Fileflare lets you attach files directly to a specific order so only that customer receives them, without affecting any other order.

Available on the Basic plan and higher. Order-attached files are added *in addition to* whatever’s attached at the product level — the customer sees both on their download page. Removing an order-attached file doesn’t affect other orders.

## When you’d use this

- You sell a personalized product (custom-named PDF, signed certificate, customized course material).
- A customer asked for a specific file as part of their order (e.g., a custom resolution of an illustration).
- You’re delivering a one-time file unique to that order — a contract, a license, a bonus.
- You replaced a customer’s file with a corrected version after the order was placed.

## Attach a file to an order

1. In Fileflare, go to **Orders** and open the order.
2. Find the **Downloads** card and click **Attach assets**.
3. Pick your method (all three live in the same modal): 
    - **Upload a new file.** Drop it on the dropzone, or click to browse. This is the default view.
    - **Select existing asset.** Opens a searchable list of everything in your library, with filters for whether an asset is already attached to an order and when it was uploaded. Tick one or more, then click **Attach to order**.
    - **Add a URL asset.** Paste a link, give it a name, and optionally a size to display. Click **Add asset**.
4. Close the modal. The files appear in the **Downloads** card immediately, grouped at the bottom under **Additional order downloads**.

![Fileflare Attach assets window on a digital order, with choices to upload a file, select an existing asset, or add a URL asset](https://fileflare.io/wp-content/uploads/2026/08/fileflare-order-asset-attach.png)    The asset is now linked to this order specifically. The customer’s download page, customer-account view, and any newly-sent email will include it.

### From the Shopify order instead

If you’re already looking at the order in Shopify, you don’t need to open Fileflare. The **Digital downloads** block has an **Upload & attach file** button with the same three choices: upload a new file, select one or more assets from your Fileflare library, or add a URL. Fileflare attaches the files and then offers to send the download email in the same flow. New uploads up to 100 MB go through this window; anything larger should use Fileflare’s own uploader. See [Fileflare on the Shopify order page](/docs/shopify-order-page-block/).

## Notify the customer

Attaching a new file doesn’t automatically send a download email. To let the customer know, click **Resend email** in the order’s page header — they’ll get a fresh download email with the updated file list.

## Cap or remove an order file

Each row under **Additional order downloads** has a **⋯** menu:

- **Set download limit** — a per-file download cap for this order. Leave it blank to use the order’s limit.
- **View in timeline** — filters the [activity timeline](/docs/order-activity-timeline/) to this file’s downloads.
- **Detach from order** — removes the file from this order only. Other orders are unaffected.

## Common issues

- **Customer didn’t see the new file** — they may be viewing an older email. Click **Resend email** to send a fresh one with the updated file list.
- **The Attach assets button shows a lock** — attaching files to orders is plan-gated. Click the lock and Fileflare tells you which plan unlocks it.
- **The file appears for past customers of this product too** — that means you attached it to the product, not the order. Detach it from the product and re-attach it through the order’s **Attach assets** button instead.
- **The upload failed partway through** — usually a sleeping browser tab or a flaky connection. Retry from the modal; for large files, use the [Fileflare uploader](/docs/methods-to-upload-add-files-to-fileflare/), which can resume.
- **I pasted a URL and no file size shows** — expected. Fileflare doesn’t host the file, so there’s no size to measure unless you type one in.
