Abstract:
A method of cloning a file system of a window web operating system by using a bitmap file, comprising the steps of (i) storing file data from a source partition in a bitmap file, (ii) compressing the data of the source partition into an image file and cloning the image file to an object disk, (iii) decompressing the compressed bitmap file of the source partition in an object partition in the object disk, enabling decompressed data to be restored to the object partition, and (iv) modifying the bitmap file subject to the size of the object partition and the physical parameters of the object disk,wherein when storing said file data from said source partition in said bitmap file, a position of a master file table (MFT) is found from a boot sector of said source partition, and then a first 20 records in the MFT are searched, so as to find a physical address and size of the bitmap file from the records, and to further obtain an actual address and size of the bitmap file.
