18.104.22.168 Application Requests a Directory Enumeration
Processing of this event is handled as specified in [MS-CIFS] section 22.214.171.124, with the following additions:
The TRANS2_FIND_FIRST2 subcommand request has been extended as specified below.
New Information Levels
Enumerating Previous Versions
An application is allowed to request an enumeration of available previous versions of a file or directory using a TRANS2_FIND_FIRST2 request (see section 126.96.36.199.1). To do this, the request MUST have the @GMT token wildcard, @GMT-*, as part of the search pattern in the FileName field and it MUST use the SMB_FIND_FILE_BOTH_DIRECTORY_INFO Information Level. This extension is not available for Information Levels other than SMB_FIND_FILE_BOTH_DIRECTORY_INFO. The client MAY<91> fail such requests or simply send the requests to the server. Because it is a path-based operation, this request follows the same previous version token parsing rules as specified in section 188.8.131.52.1.
The message is sent to the server.
