docs/docs/en/file-manager/storage/aliyun-oss.md
A storage engine based on Aliyun OSS. Before use, you need to prepare the relevant account and permissions.
:::warning Note
This engine does not support private access. After a file is uploaded, NocoBase generates a directly accessible URL, and anyone who has that URL can access the file.
Even if the OSS bucket itself is private, the built-in Aliyun OSS engine does not generate temporary signed URLs for file access. If you need private access, use S3 Pro. If historical files already exist, see Migrate to S3 Pro.
