Embodiment Construction

[0014] refer to figure 1 As shown, it is a schematic diagram of the application environment of the preferred embodiment of the system for merging the storage space of the U disk according to the present invention. The system 10 for merging the storage space of the USB disk runs in the USB hub 11 . The USB hub 11 is connected to a data processing device (such as a computer) 14 and includes a plurality of USB interfaces 12 for connecting a U disk 13 . By running the system 10 for merging the storage space of the USB disks, the user's operations on each USB disk 13 can be simplified to one large-capacity USB disk.

[0015] refer to figure 2 shown, is figure 1 The functional block diagram of the system that combines the storage space of the U disk in the system. The system 10 for merging storage spaces of USB flash drives includes a scanning module 200 , a detection module 210 , a virtualization module 220 , a linking module 230 , a first copying module 240 and a second copyi...

Abstract

Disclosed are a USB (universal serial bus) flash disk storage space merging system and a method. The USB flash disk storage space merging system runs in a USB concentrator and comprises a scanning module, a detecting module, a virtual module, a linking module, a first copying module and a second copying module, the scanning module is used for scanning USB interfaces of the USB concentrator so as to detect various USB flash disks inserted into the USB interfaces, the detecting module is used for detecting capacities, contained files and residual spaces of the USB flash disks, the virtual module is used for creating a virtual USB flash disk, the capacity of the virtual USB flash disk is the sum of the capacities of all the USB flash disks, the virtual USB flash disk contains the files of all the USB flash disks, the linking module is used for creating linking relation of the various files of the virtual USB flash disk and the USB flash disks, the first copying module is used for writing a file into the corresponding USB flash disk according to the residual space of the various USB flash disk, adding the file to the virtual USB flash disk and creating the linking relation between the file and the USB flash disk, and the second copying module is used for transmitting a file from the corresponding USB flash disk according to the linking relation of the file and the USB flash disk when the file is copied from the virtual USB flash disk. By the aid of the USB flash disk storage space merging system and the method, the multiple USB flash disks can be merged to form the large-capacity USB flash disk for users.

Description

technical field [0001] The invention relates to a storage system and method, in particular to a system and method for merging storage space of a USB disk. Background technique [0002] With the popularity of U disks, many users have multiple U disks. When users use these U disks to store files, they need to consider the capacity and remaining space of each U disk, and choose a suitable U disk to store data according to the size of the file. Since each U disk is relatively independent, it is very inconvenient for users to use. In particular, if the file is relatively large and exceeds the capacity of a single USB flash drive, it is necessary to manually divide the file, copy the split file to multiple USB flash drives, and then copy each part of the file from multiple USB flash drives when restoring the file. part to combine. The copying of the above-mentioned large files requires special segmentation and combination software, and the operation is cumbersome, which is ofte...
