Problems solved by technology
[0005] However, the present inventor found in the process of implementing the present invention that if the data needs to be extracted and stored in the hard disk again in the form of a file in the process of generating a preview of deleted files, the space of the hard disk needs to be occupied, which just It may overwrite other deleted data in the hard disk, making the overwritten deleted data less recoverable, or even impossible to recover, resulting in a certain degree of data loss
[0006] Therefore, a technical problem that urgently needs those skilled in the art to solve is how to provide a more effective solution for generating file previews, so as to avoid affecting the recoverability of other deleted files in the process of generating previews

Embodiment Construction
[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.
[0044] see figure 1 The method for generating a file preview provided by the embodiment of the present invention includes the following steps:
[0045] S101: Scan the hard disk to generate a list of deleted files;
[0046] Deleted files are invisible to users, and users cannot operate on deleted files without special operations. Therefore, for the disk partition, the files marked as "deleted" can be found first, and these files can be displayed to the user in the form of a list. For exampl...

The invention discloses a method and device for generating file preview. The method comprises the following steps of: scanning a hard disk to generate a deleted file list; obtaining a data region of the data thereof aiming at a deleted visual file in the deleted file list; reading the data into a memory from the data region; and decoding the data in the memory to generate preview of the visual content of the deleted visual file. Through the method and the device, the recoverability of other deleted files can be prevented from being influenced during preview generation.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for generating file previews. Background technique [0002] With the rapid development of science and technology and the progress of the times, computer equipment has become an essential tool for almost everyone. People can save, view, modify, delete and other operations on files through computer equipment. However, in practical applications, there may be accidental deletion of files, and in this case, it is necessary to restore the deleted files. [0003] In the process of recovering deleted files, since deleted files are invisible to the user, a file recovery tool is required to scan the hard disk and provide the deleted files in the hard disk to the user in the form of a list. The user selects the files to be restored, and then performs subsequent restoration operations on the files selected by the user. However, the deleted file list usually only cont...
