The basic principle and analytical introduction of file shredding

"Smash file" as the name suggests, is the computer on the file completely deleted, leaving no traces. Using some file shredding tools, you can do this. such as the rising card card or 360 software.

Shredding files is not the same as deleting files directly, which is from the Windows file system. The Windows file system includes FAT systems such as FAT12, FAT16, FAT32, and the NTFS file system. In the FAT file system, if you create a file, you need to open a "distribution table" on disk, just like a library bibliography. This table includes a pointer to the address of the contents of the file. The system then reads and writes the file at the address it points to. At the same time, other files, if they are to be created, are prohibited from pointing at this address to prevent file confusion. and the operating system to delete the file is much more convenient: directly to the "Bibliography" to destroy it. The address that the "Bibliography" points to is considered empty. The data in the computer is made up of binary, which appears as "concave" and "convex" on the disk. Because the system cannot predict the details of the file that will be deposited, the contents of the file can be considered random. By mathematical Knowledge, "0" and "1" on the disk have no effect on the speed of the re-writing information.

Our information may be detected by uninvited visitors, can be based on the clues on the disk, to re-establish the entire file, or a part of the file, thus spying on our privacy. That would be bad for us. Therefore, there is the concept of "file shredding".

"File Shredding" is the deletion of content and "bibliography" so that the contents of the file are not known to anyone. And the general file shredding software can be word, WPS and other tools in the history and system created temporary files deleted, so that no one can know our privacy.
