Cloud file indexing system and method thereof

The present invention relates to a cloud file indexing system and method thereof, and more particularly to a cloud file indexing system and method for integrating basic information of a user device and a plurality of files of a cloud storage space.

Nowadays, the world has entered the era of the cloud. There are many cloud services available to a wide range of users, including the popularity of user devices (User Equipment, UE) such as smart phones, tablets and personal computers. Many users have the requirement of "one file for multiple terminals". Therefore, "cloud hard disk" with "no local hard disk space and access anytime, anywhere" feature is arguably the most popular cloud service. one.

Since most of the cloud storage platforms (such as Google Drive, Dropbox, SugarSync, Skydrive, Box.net, etc.) provide limited free storage space for users, there is a certain amount of data to be stored in the cloud storage platform. Most users who use the cloud hard disk but don't want to spend too much money will use more than two cloud storage platforms.

The above "one person saves the cloud" approach allows users to reduce the expansion order The cost of the cloud hard disk capacity of a cloud storage platform, but after long-term use, users tend to forget the storage location of some specific files, and it is easy to repeatedly store the same files on the cloud hard disk of different cloud storage platforms, resulting in The waste of space.

Moreover, if the files of the cloud hard disks of different cloud storage platforms are not synchronized to the hard disk of the user device, the files between different cloud storage platforms cannot be searched. However, if it is convenient to find files and synchronize all the files of the cloud storage platform to the hard disk of the user device, the hard disk space of the user device will be wasted. If you go directly to the website of different cloud storage platforms to query (or search), it is also difficult to find the files of the user device and different cloud storage platforms at the same time.

1 is a schematic diagram showing a first usage mode of the cloud file indexing system 1 of the prior art, and FIG. 2 is a schematic diagram showing a second usage mode of the cloud file indexing system 1 of the prior art. .

As shown in FIG. 1, the first usage mode of the cloud file indexing system 1 is "the mode of the network interface". In the first usage mode, the cloud file indexing system 1 can detect basic information (such as name, modification date, size or location) of files stored in at least two cloud storage platforms (such as Amazon S3 and Dropbox), but However, it is impossible to find out the basic information of the files stored by the user device (local side).

Moreover, as shown in FIG. 2, the second usage mode of the cloud file indexing system 1 is "the connection state of the network disk drive". In the second usage mode, the cloud file indexing system 1 can detect the basic information of the file stored by the user device (local side), but cannot find the cloud storage. Basic information about the files stored on the platform.

In addition, in the cloud file indexing system 1, the two different usage modes shown in FIG. 1 and FIG. 2 need to be separately used, and in the network connection state, the cloud storage spaces and the use can be separately queried. The basic information of the file of the device, the user can not simultaneously query the cloud storage space and the user through the cloud file indexing system 1 in the single use mode and in the offline state or the unstable network state. Basic information about the file of the device.

Therefore, how to overcome the problems of the prior art mentioned above has become a problem that is currently being solved.

The invention is a cloud file indexing system and a method thereof, which can integrate basic information of a file of a user device and a different cloud storage space through a file index table.

The cloud file indexing system and the method thereof may include: transmitting, by the transmitting module, the fourth file to the first cloud storage space, the second cloud storage space or the third cloud storage space for storage, and the control module is configured by the control module The first cloud storage space, the second cloud storage space or the third cloud storage space is returned to the basic information of the fourth file, and the basic information of the fourth file is recorded by the index module into the file index table. To update the file index table.

The second file and the third file may be first stored in the user device, and the second file and the third file are respectively transmitted to the first cloud storage space by the transmitting module through the network. The second cloud storage space is stored.

The storage module of the user device can be a database or a memory, the first The cloud storage space or the second cloud storage space may be a cloud storage disk of the cloud storage platform, and the basic information of the first file, the second file or the third file may include a file name, a file storage location, a file size, or an archive date. Wait.

The cloud file indexing system includes a selection module, and the system and method thereof include: selecting the second file and the first cloud storage space for storing the second file by using the selection module to transmit the transmission module Transmitting the second file to the first cloud storage space for storage; and selecting the third file and the second cloud storage space for storing the third file by using the selection module to transmit the second cloud file The third file is transferred to the second cloud storage space for storage.

The cloud file indexing system includes a receiving module, and the method and method can include: receiving, by the receiving module, basic information of the second file returned by the application interface of the first cloud storage space, and receiving the The basic information of the third file returned by the application interface of the second cloud storage space.

The cloud file indexing system and the method thereof may include: querying, by the query module, the file index table of the user device in the network connection state, the network offline state, or the network instability state, from the file index The basic information of at least one of the first file to the third file is found in the table.

It can be seen from the above that the cloud file indexing system and the method thereof of the present invention mainly transmit and store at least two files into at least two cloud storage spaces, and store the files of the user device (local end) with the clouds. The basic information of the file of the storage space is recorded to the file of the user device. In the table.

Therefore, the present invention can save the storage space of the file of the user device, and can conveniently manage the file of the user device and the different cloud storage space, and can also easily query the user device and the cloud storage. The basic information of the space file is also available for the user to delete the file stored in the user device and the different cloud storage space to avoid wasting storage space.

Moreover, the present invention can enhance the basic information of the user device (local end) and the files of different cloud storage spaces through a single file index table or a single usage mode, thereby enhancing the user querying the user device and The convenience of the files of the cloud storage space, and the improvement of the cloud file indexing system of the first and second figures of the prior art, respectively, are required to obtain the cloud storage space and the user device respectively through two different usage modes. The shortcomings of the basic information of the file.

In addition, the file index table of the present invention is stored in the user device (local end), so the user can be anytime, anywhere, whether in the network connection state, the network offline state or the network instability state. The user device queries the basic information of the user device and the files of the cloud storage space, and further improves the cloud file indexing system of the first and second figures of the prior art only when the network is connected. The shortcomings of querying the basic information of the user device and the files of the cloud storage space.
