Virtual file system based on cloud computing

Abstract

The invention discloses a virtual file system based on cloud computing. The virtual file system based on cloud computing comprises a serving terminal and a client terminal, wherein the serving terminal is composed of a file virtualizer, a file processing center, a file system interface, a file transmitter, a user interface, a database, a thumbnail managing module, a file format converting module and a rubbish cleaning device and the client terminal is composed of a receiving and transmitting module, a terminal simulation virtual file system and a file interaction module. The serving terminal interacts with one or more client terminals, so that the functions of carrying out asynchronous operation and asynchronous reading and writing on cloud terminal server files are provided for the system and applications based on the web. An effective solution is provided for the application of HTML5 to support a file system and an API is opened for the application of the third party. The auxiliary technology supporting file format conversion provides a substitute scheme when files which are not compatible with the HTML5 are browsed or edited. A file storage scheme of a cloud terminal is adopted so that a user can manage, browse and edit files without domain limitation, terminal limitation and platform limitation under network connection.

Description

technical field [0001] The invention relates to a virtual file system based on cloud computing, which is applied to systems and applications based on Web. Background technique [0002] With the rapid development of the Internet, it has now entered the post-Web2.0 era, and human-computer interaction and human-network interaction have become the norm, and some HTML5-based Web Apps (Web-based systems and applications) have followed one after another. Compared with Native App (a third-party application based on the local operating system of smartphones such as IOS, Android, and Windows Phone and written and run using native programs), it has no installation, low development costs, cross-platform and cross-terminal, and iterative updates Easy and other advantages make it very likely to become the world in the future. However, due to the consideration of security issues, especially when running on the browser, the HTML5 technology has very limited operations on the file system, a...

Problems solved by technology

However, file synchronization on terminals, especially terminals of different brands, is rather cumbersome. If you need to browse and edit the same file on different terminals, you usually use USB, WIFI, and Bluetooth connections to transfer files between terminals. exchange, which is quite inconvenient

At present, there are also many file storage systems (or applications) based on cloud computing, but unfortunately they cannot be edited and can only be browsed, which cannot meet office needs.
