背景技术 Background technique

随着计算机技术的发展,移动存储装置,特别是闪存盘正在得到广泛的应用。 With the development of computer technology, removable storage devices, in particular flash drives are widely used. 但由于闪存盘的容量较小,成本较高,对闪存盘进行压缩存储,具有重要价值。 However, due to the small flash drive capacity, higher cost, flash memory disk compression, great value. 目前对闪存盘进行压缩存储的方法有下属两种类型:一种是人工调用压缩软件,并按压缩软件的操作界面,对要存储的数据进行压缩操作,然后再存入移动存储装置中;或人工调用解压缩软件,对从移动存储装置中取出的数据进行解压缩。 The method currently stored in the flash drive with a compressed under two types: one is an artificial calling compression software, interface software compression press, for compressing data to be stored in the operation, and then stored in the mobile storage means; or artificial call decompression software, data retrieved from the mobile storage device decompressed. 此时用户必须熟悉压缩软件的使用,并且人工进行相应的操作。 At this time, the user must be familiar with the use of software compression, and manually perform a corresponding operation.

另一种是在Windows XP操作系统环境下,使用系统内置的Zip压缩文件夹功能。 The other is in the Windows XP operating system environment, use the built-in Zip compression system folders. 此时用户需先对移动存储装置进行Zip文件夹创建,进行相关属性的配置等,操作亦很麻烦。 At this time, the user must first removable storage device Zip folder creation, and other configuration related properties, also very troublesome operation.

发明内容 SUMMARY

本发明的目的,是为用户提供一种新型的能够对所存取的数据自动进行压缩和解压缩的移动存储系统。 Object of the present invention is to provide a novel data can be accessed by the user automatically removable storage system of compression and decompression. 在这种系统中,存取数据的压缩和解压缩操作,完全由系统自动进行,对用户是完全透明的。 In such systems, the compression and decompression of data access operations, completely automatically by the system, is completely transparent to the user.

使用本发明,用户对闪存盘进行计算机文件存取时,完全如没进行压缩/解压缩时一样操作,(象原来一样地使用操作系统的图形用户界面,并进行与原来相同的操作),但他的闪存盘的容量却好像大了许多倍,例如一个64MB的闪存盘,可能存512MB或更多的数据,而且存入和取出的数据都和原来完全一样。 When using the present invention, a user of a computer file access flash drive, exactly as no compression / decompression operations, like, (as originally used as an operating system graphical user interface, and the same operation as in the original), but his flash disk, but it seems like a lot of times, for example, a 64MB flash drive, 512MB or more may save data, and deposit and withdrawal data are exactly the same as the original.
