Further, cloud platform provides virtual machine service to user, when user is from local machine upload file, uploaded by web terminal, when user downloads the file into local machine, downloaded by web terminal, built-in file: the public of each virtual machine, the shared file center of the corresponding web terminal of this file, the content shown in described file comes from the shared file distribution table of central field, but only showing wherein " whether being duplicate of the document " field is the part of " no ", and the just file shortcut shown in file, when user wants to be uploaded by virtual machine, download, during deletion action, the operation of rear end still passes through Internet Transmission, when user wants from virtual machine upload file, only need file copy in corresponding file, when user downloads the file into virtual machine, only need to copy out from corresponding file.
Herein, public is the name of file, gets the meaning of its Chinese " public ", just can know that the effect of this file is " sharing ", i.e. the place of Storage sharing file by name.In practical implementations, developer can name arbitrarily.
The present invention compared with prior art, has following beneficial effect:
The present invention is by selection central field, utilize central field to safeguard that shared file distribution table ensures the transparency to user, when certain territory user uploads shared file, central field distribution table increases record, when user downloads shared file, this file position can be inquired about in the distribution table of central field, thus achieve the object using minimum cost to reach cross-domain file transfer management.
Further, by arranging public file in each virtual machine, corresponding shared file center, display wherein " whether being duplicate of the document " field is the partial sharing file distribution table of " no ", user uploads, download file time, only need file copy in this file, thus realize virtual machine and the machine to the slitless connection of file operation.
Accompanying drawing explanation
