Abstract
A movable storage system for automatically carrying out data compression and decompression can be used to easily access times of information as its scaled volume to and from the movable storage device without any manual compression and decompression.
Description
Technical field
Field under the present invention is a computer technology.
Background technology
Along with development of computer, flash memory device, particularly flash disk is widely used.But because the capacity of flash disk is less, cost is higher, and flash disk is compressed storage, has important value.At present the method that flash disk is compressed storage has two types of subordinaties:
A kind of is manually to call compressed software, and by the operation interface that compresses software, the data that store is carried out squeeze operation, and then deposit in the flash memory device; Or manually call PKUNZIP, the data of taking out from flash memory device are decompressed.This moment, the user must be familiar with the use of compressed software, and manually operated accordingly.
Another kind is under Windows XP operating system environment, the Zip compressed document file function that using system is built-in.This moment, the user needed earlier flash memory device to be carried out the establishment of Zip file, carried out the configuration of association attributes etc., operated also pretty troublesome.
Summary of the invention
Purpose of the present invention is to provide a kind of novel mobile memory system that can carry out compression and decompression to the data of institute's access automatically for the user.In this system, the compression and decompression of access data operation is carried out automatically by system fully, is fully transparent to the user.
Use the present invention, when the user carries out the computer documents access to flash disk, operate fully when not carrying out compression/de-compression, (use the graphic user interface of operating system as Yuan Lai, and carry out and original identical operations), but the capacity of his flash disk is as big manyfold, for example flash disk of a 64MB, may deposit 512MB or more data, and the data that deposit in and take out all and just the same originally.
Description of drawings
Technical scheme of the present invention, as depicted in figs. 1 and 2,
Fig. 1. be the formation of system
Fig. 2. be the workflow of system
Embodiment
As shown in Figure 1, system of the present invention is made of computing machine and flash memory device two parts.The computing machine here can move Windows, Linux or other operating system; The flash memory device here comprises:
(1) interface module.USB interface or other interface as extensive employing.
(2) control module.The control module here is except that the conventional func of flash memory device, still need and have " automatically performing " function, for example, be made as compression and decompression assembly installation procedure with carrying out option among the autorun.inf of flash disk, can insert main frame to flash disk and be modeled as CD, automatically perform autorun.inf file in the virtual CD by host operating system, start compression and decompression assembly installation procedure automatically, in compression and decompression assembly loading of operating system.
(3) storage medium.As flash chip or other storage medium etc.
(4) be preset at specific software in the above-mentioned storage medium.It comprises:
A. compressed and decompressed assembly.This assembly will be installed in the computer operating system by its installation procedure.It can the capturing operation system to the read-write operation of flash memory device, and operating system desired to deposit in the computer documents of flash memory device or the computer documents that desire is taken out from flash memory device, carry out compression/de-compression automatically.
B. the installation procedure of compressed and decompressed assembly.When the control module of flash memory device had " automatically performing " function, this installation procedure can be called automatically, and above-mentioned compressed and decompressed assembly is packed in the computer operating system automatically; When the control module of flash memory device did not possess " automatically performing " function, this installation program also can be finished the installation of compressed and decompressed assembly in operating system by manually starting.
The workflow of native system as shown in Figure 2, operation steps is described as follows:
(1) flash memory device is connected into computing machine;
(2), call the compression and decompression assembly installation procedure that is preset in the flash memory device storage medium automatically by the automatic executing function of flash memory device control module;
(3) in the above-mentioned installation procedure detection computations machine system whether the compression and decompression assembly has been installed,, the compression and decompression assembly has been installed in computer system then if this assembly is not installed in the system;
(4) whether compression and decompression assembly monitor user ' has read-write operation to flash memory device;
(5) when the user by for example pasting or drag operation, when flash memory device writes file or catalogue, by operating system to compression and decompression components request data stream interface, compression and decompression assembly initialization data stream interface, and when operating system is called write operation, use compress technique, finish compression synchronously, and the data after will compressing return to operating system to source data, operating system writes flash memory device with data after receiving data after the compression;
(6) when the user when for example copy or drag operation read the file of flash memory device or catalogue, by operating system to compression and decompression components request data stream interface, compression and decompression assembly initialization data stream interface, and when calling read operation, operating system uses decompression technique, finish decompression synchronously to the packed data in the flash memory device, and the data after will decompressing (file or catalogue) return to operating system, after operating system is received data after the decompression, data are write copy or drag to the destination catalogue, and whether announcement compression and decompression assembly deletes the packed data in the flash memory device;
(7) in the operation of the 4th step, operating system does not have read-write operation, or when read-write operation has been finished in the operation of the 5th or the 6th step, returns to the operation of the 4th step.
Annotate: when the flash memory device control module does not possess automatic executing function, can be by manually calling installation procedure, in compression and decompression assembly loading of operating system.This moment, other (1)-(7) operation was identical except that above-mentioned (2) operation.
