Abstract

The invention discloses a method for establishing or modifying files and a terminal device. The method is applied to the terminal device. The terminal device comprises a storage unit, wherein the storage unit stores system data and user data required by system recovery in a first storage region. The method comprises the steps as follows; when a first file is established or modified, whether a second file corresponding to the first file exists in the first storage region is judged; if the second file corresponding to the first file exists in the first storage region, the first file is saved in a second storage region of the storage unit; and a first mark is added in a file header of the first file.

Description

technical field [0001] The invention relates to a terminal device and a method for creating or modifying a file. Background technique [0002] Currently, in order to eliminate the intrusion of malicious programs such as viruses or Trojan horses, or to prevent the operating systems of terminal devices such as PCs, notebooks or tablet computers from becoming more and more bloated, the operating systems of terminal devices (such as Windows or Android) can usually provide a system recovery program or function. . For example, some system recovery programs or functions usually search for a certain file in a folder in the system recovery area (by checking whether the file can be opened) whether there is a corresponding file in the corresponding folder. If the corresponding file exists, the corresponding file is deleted, and the operating system is restored using the file in the system recovery folder. Also, if the corresponding file does not exist, the operating system is restor...
