Adobe Experience Manager Assets

zp288 · 7/6/25

Hi everyone,
I'm trying to download a large asset (around 40GB) from Adobe Experience Cloud. However, after downloading approximately 1GB, the process fails with a "connection lost" error — even though my internet connection remains stable and uninterrupted. I’ve tested this on both Safari and Chrome, and the issue persists in both browsers.

I also tried using download managers (such as IDM and Free Download Manager), but they either fail to capture the link properly or still encounter the same interruption.

Is there a recommended method for downloading large files from Adobe Experience Cloud?
Would using a desktop application like Adobe Bridge help in this situation?
Alternatively, is it possible to split the asset into smaller parts for easier download?

I'd really appreciate any insights or suggestions from those who’ve experienced a similar issue.

Thanks in advance!

Following the steps below will help you successfully download large assets from AEM as a Cloud Service:

Split the Asset into Smaller Parts:
- Use AEM’s DAM Update Asset workflow or manually split the file into smaller segments (e.g., using zip with volume mode) before uploading.
  This makes large assets easier and more reliable to download.
Use cURL for Programmatic Download:
- You can use a cURL command with an access token to download the asset directly:

curl -L -O -H "Authorization: Bearer <access_token>" \
"https://author-pXXXX.adobeaemcloud.com/api/assets/my-large-asset.zip"

Make sure to first retrieve a signed download URL using the [AEM Assets HTTP API](https://developer.adobe.com/experience-manager-apis/documentation/assets-http-api/), as direct asset URLs are often time-limited.
Avoid Browser-Based Downloads for Large Files (>2GB): Browser downloads often fail for large assets due to timeout or signed URL expiration.

I am just a standard user. I am having the problem because it is not being uploaded in parts as you said.

The link above does not work.

Can you please explain to me how to download with curl, thinking from an end-user perspective?

@zp288

This must be due to default timeout of 60 seconds on AEMaaCS. https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/implementing/dev...

How was this large asset uploaded to DAM?

@aanchal-sikka
Thank you for your response and the reference link you shared. I don’t have exact information on how the asset was uploaded to the DAM. The content was shared with me through my company’s Brand Portal interface. Therefore, I’m not sure which method was used during the original upload (e.g., direct upload, AEM Desktop App, or an automated integration). Thanks again — I truly appreciate your input!
