Abstract

The invention discloses a file identification method and device, a storage medium and a processor. The method comprises the following steps: acquiring a to-be-identified compressed file, wherein the file type of the to-be-recognized compressed file is recognized, and the file type comprises a roll-divided compressed file and a complete compressed file; decompressing the to-be-recognized compressed file based on the file type of the to-be-recognized compressed file to obtain a to-be-recognized non-compressed file; and recognizing the content of the to-be-recognized non-compressed file. According to the method and the device, the technical problem that the roll-divided compressed file cannot be identified is solved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a file identification method, device, storage medium and processor. Background technique [0002] When transferring a large compressed file, such as sending an email, the attachment of a single email is too large, resulting in a long transmission time, and the final transmission fails, and all transmissions fail. In addition, the transmission and transfer of super-large compressed files is extremely time-consuming and system resource-intensive, and has a great impact on the overall throughput of the system in a high-concurrency environment. The goal is to compress files into volumes and send them in batches to improve system performance. [0003] However, for sub-volume compressed files, existing methods cannot effectively identify and scan them. [0004] For the above-mentioned problem of not being able to identify the sub-volume compressed files, no effective solution has been propos...
