Embodiment 1

[0084] refer to figure 1 , showing Embodiment 1 of the file or folder search method of the present invention, comprising the following steps:

[0085] Step 101, read the content of the master boot record area to obtain the partition format of the hard disk.

[0086] The operating system can call the API CreateFile to open the corresponding hard disk device or partition. Thereby, the handle of the hard disk or the partition is obtained, and then the content of the master boot record area (MBR, Master Boot Record) is read.

[0087] Read the content of the master boot record area to determine the partition format of the hard disk. The logo of the hard disk partition format is recorded in the master boot record area, and the hard disk partition format can be determined by reading the content of the master boot record area. Currently, Windows partition formats include FAT12, FAT16, FAT32 and NTFS (New Technology File System). Among them, for the first three types, all files and ...

Abstract

A method for finding files or folders, including the following steps: acquiring a hard disk partition format; acquiring the recording addresses of all the file or folder attributes in the hard disk according to the hard disk partition format, and reading all the file or folder attributes into an internal memory according to the recording addresses of the file or folder attributes; and traversing and finding all or part of the files or folders in all the file or folder attributes read into the internal memory.Also provided is a device for finding files or folders for realizing the method above.The method and device for finding files or folders in the present invention can find files or folders rapidly, and reduce occupied computer resources.

Description

technical field [0001] The invention relates to the technical field of computer storage data search, in particular to a file or folder search method and device. Background technique [0002] The hard disk is the most commonly used storage device on the computer nowadays. The files or folders in the computer are stored in the hard disk in the form of file records. A hard disk can be divided into multiple partitions. Partitioning is essentially a formatting of the hard disk. When we create a partition, we have already set the physical parameters of the hard disk, and specified the storage location of the hard disk Master Boot Record (Master Boot Record, generally referred to as the Master Boot Record area) and the boot record backup. [0003] Usually, searching for a specified or all files or folders from the hard disk under Windows is realized by calling the two APIs (Application Programming Interface, Application Programming Interface) of FindFirstFile and FindNextFile. I...
