Abstract
A method, system, and server for issuing directory tree data and a client. The method includes: pre-storing Identities (IDs) for data blocks obtained by dividing directory tree data according to an agreed protocol, and generating and storing validity IDs for the data blocks according to the agreed protocol; receiving, by a directory tree server, an ID and a validity ID of a data block that the client requests to download, and querying for a validity ID of a data block having the same ID at a directory tree server side. If the validity ID of the data block having the same ID at the directory tree server side is the same as the validity ID received from the client, issuing a matching success message to the client; otherwise, issuing, a matching failure message and the data block at the directory tree server side having the same ID to the client.
