Abstract

The invention discloses a file access method, electronic equipment and a readable storage medium, and belongs to the technical field of terminals. The method comprises the following steps: receiving a read-write operation of a second electronic device on a file based on a temporary modification file, wherein the temporary modification file comprises to-be-modified and / or modified contents in the file; receiving an access request of third electronic equipment to the file, wherein the access request carries indication information of the access mode and the first file piece information; Under the condition that the indication information indicates the read-only mode, if the temporary modification file comprises the first file piece indicated by the first file piece information and the first file piece is modified, reading the first file piece from the temporary modification file; and sending the read first file piece to the third electronic equipment. According to the method, access operations such as read-write and reading are carried out based on the temporarily modified file, a read-write lock mechanism does not need to be added, and access of multiple pieces of electronic equipment to the file at the same time is achieved.

Description

technical field [0001] The present application relates to the technical field of terminals, in particular to a method for accessing files, electronic equipment and a readable storage medium. Background technique [0002] In the scenario where multiple electronic devices access files, when electronic device A is modifying a file on electronic device B, if another electronic device C reads the file, it will read an intermediate state of the file. If the electronic device C needs to perform a verification operation on the read file, since the read file is not an original complete file, it will be confirmed as an illegal file, thus causing the operation to fail. [0003] In related technologies, in order to avoid the above problems, a read-write lock mechanism is generally used in the process of reading and writing files, that is, when electronic device A modifies a file on electronic device B, electronic device B locks the file through the read-write lock mechanism. This file ...
