Problems solved by technology

[0003] The inventor finds in the process of realizing the present invention, there is following shortcoming at least in the prior art: the virtual disk in the prior art (as the virtual disk under Windows operating system) is all based on file mapping, adopts file mirror technology, will need All files that are virtualized as disks are written in an image file, that is, the OS (Operating System, operating system) maps files to disks, and all data is actually stored in a local disk image file. User operations in this file, Equivalent to disk-level operations, since all the contents of virtual disks actually exist in the file, distributed storage cannot be achieved; users cannot organize their own data through flexible disk views

example 1

[0061] The file \a\a.txt in the user's virtual disk corresponds to the real file c:\m\m.txt in the user's local disk. When the user browses the file a.txt, the local c:\m\m.txt is opened by operating the proxy unit file, returns the data to the user, and what the user sees is actually the m.txt file.

example 2

[0063] The file \b\b.txt in the user virtual disk corresponds to the real file \192.168.1.2\c:\m\m.txt in the local area network. Operation proxy unit communication, the operation proxy unit opens the c:\m\m.txt file, and transmits the data to the user’s local proxy operation unit, and then returns the data to the user. What the user sees is actually \192.168.1.2\ c:\m\m.txt file.

example 3

[0065] The file \c\c.txt in the virtual disk of the user is compared to the real file http: / / www.mm.com.cn / mm.txt in the Internet. Read the file content of http: / / www.mm.com.cn / mm.txt and return it to the user. What the user sees is actually the file http: / / www.mm.com.cn / mm.txt.

[0066] Wherein, the operation agent unit 140 includes:

[0067] The receiving module is configured to receive user operations on virtual files in the virtual disk.

[0068] The parsing module is configured to parse the user's operation on the virtual file in the virtual disk, and complete the conversion from the virtual file to the real file according to the mapping relationship between the virtual file and the real file.

[0069] The agent module is used to operate the real file, obtain the data of the real file, and return the data to the user.

[0070] Wherein, the analysis module includes:

[0071] The parsing sub-module is configured to perform reverse parsing on the user's operation on the v...

Abstract

The embodiment of the invention discloses a virtual disk system, a virtual disk implementation method and terminal equipment. The system comprises a virtual disk driving unit, a view organization unit and a database unit, wherein the virtual disk driving unit is used for simulating the real disk driving and realizing a virtual disk in an internal memory, the view organization unit is used for providing an interface used by users to organize the virtual disk view and constructing the mapping relationship from virtual files to real files in the virtual disk, and the database unit is used for storing the mapping relationship from the visual files to the real files. The technical scheme of the invention does not need to realize the virtual disk through image files, so the storage space is saved, the original data information does not need to be modified, the consistency of the data can be maintained, in addition, users can freely organize the disk view, and the files of Internet / local area network can be mapped to the local places through mapping at the same time, so the network characteristics of the files can be shielded for users.

Description

technical field [0001] The invention mainly relates to the field of computer virtual disks, in particular to a virtual disk system, a virtual disk realization method and terminal equipment. Background technique [0002] With the rapid development of computer technology and the deepening of informatization, computer hardware and software have been vigorously developed. With the increase of users' personal data, it often leads to very deep directories when sorting data, and users hope to view them in shallow directories. Need data, but do not want to modify the directory structure of their own data, virtual disk technology (VHD, Virtual Hard Disk) appeared in the process of rapid computer development. [0003] The inventor finds in the process of realizing the present invention, there is following shortcoming at least in the prior art: the virtual disk in the prior art (as the virtual disk under Windows operating system) is all based on file mapping, adopts file mirror technol...
