MiChuan is a common feature in the cloud storage industry, and Alibaba Cloud Disk indeed has it. We can first dispel the user's doubts with a positive answer, and then explain the principle, operation steps, dependent conditions, and precautions in a clear and structured manner.
I have thought about the need to explain the technical principle of Miaochuan (hash value comparison), otherwise users may not understand why it can achieve Miaochuan. The operation steps should be simple and clear, avoiding redundancy. The dependency conditions section should explain the importance of file uniqueness, otherwise users may be confused about failure scenarios. Finally, I will add official channel suggestions to reflect objectivity.

Yes, Aliyun Disk supports the instant transfer function.
When you upload a file, Aliyun Disk will first check if an identical file already exists on the server. If it does, it will directly "link" that file to your account instead of uploading it again. This process is almost instantaneous, hence the name "Instant Transfer".
Principles and characteristics of Miaochuan:
Based on file hash values: The system identifies files by calculating their "digital fingerprints" (such as MD5, SHA1, and other hash values). If the hash values of two files are identical, the system considers them to be the same file.
Save time and data: This is the biggest advantage of Miaochuan. No matter how large the file you upload is, as long as it exists in the cloud, it can be instantly completed without consuming upload bandwidth.
Rely on "uniqueness":
The prerequisite for successful Miaochuan is that an identical file has already been uploaded by another user on the Alibaba Cloud server.
If you upload a unique file that has never been uploaded before (such as a private video you filmed yourself or a document you edited), it cannot be uploaded instantly and requires a full upload.
How to determine whether a fast transfer has been triggered?
When uploading a file, you will see an upload progress bar. If the progress bar quickly jumps from 0% to 100% within a few seconds, and there is no obvious network upload waiting during the process, it is likely that Miaochuan has been triggered.
Important precautions:
Privacy and Security: The Miaochuan mechanism relies on precise matching of file content. Alibaba Cloud Disk officially adheres to strict security and privacy policies to ensure user data isolation. Miaochuan merely establishes a "reference" to the file, and it does not allow other users to access your private files. Your files are still stored in your personal private space, accessible only to you and those you share with.
File review: For files involving infringement, violations, or sensitive content, even if the content is identical, they may not be able to be instantly transferred due to security policies, or may be detected and processed by the system after uploading.
summary
The instant upload feature of Alibaba Cloud Disk can significantly enhance upload efficiency, particularly for commonly uploaded files such as software installation packages, public movie episodes, and music. However, for files that are unique to individuals, the normal upload process is required.
