example 1

[0088] Example 1: In the case that all files are stored in the root directory of the local disk, the types of access nodes contained in the generated file index tree can only be root nodes and leaf nodes, the root node maps to the root directory, and the leaf nodes map to files .

example 2

[0089] Example 2: The file index tree can also contain root nodes, child nodes and leaf nodes, for example, in image 3 In the file index tree shown, the root node can be mapped to the root directory C disk, child node A can be mapped to the folder PATH1 of the C disk under the root directory, and the leaf node E1 under the child node A can be mapped to the file under the file PATH1 E0.

example 3

[0090] Example 3: When the root node has no mapping relationship, the second-level nodes below the root node can be mapped to multiple root directories, for example, in image 3 In the file index tree shown, the root node may not be mapped to any file or folder. In the second-level nodes under the root node, access node A can be mapped to C drive, access node B can be mapped to a memory file, and access node C can be mapped to a certain file or folder in the network storage space, and access node D can be mapped to a certain folder on the C drive.

[0091] According to whether there are duplicate files in the file before pooling, the above methods of generating access nodes include the following two methods:

[0092] For duplicate files before pooling, only one file is stored in the above pooling process, but multiple leaf nodes need to be generated. Example: There are two identical duplicate files E0 and E0-1 in the file before pooling, and only file E0 is stored in the pool...

Abstract

The invention relates to a file operation method and device, a storage medium and electronic equipment. The method comprises the steps: obtaining an operation request of a target file system for a target access node, and judging whether an adapter type of the target access node can execute the operation request or not; when the adapter type of the target access node can execute the operation request, specifying a corresponding adapter to execute the operation request; and when the adapter type of the target access node cannot execute the operation request, inheriting an adapter capable of executing the operation request from the father node of the target access node, and executing the operation request. Thus, multiple target file systems can operate the target files or folders through thetarget access node of a file index tree and map the target files or folders to the same file through different nodes of the file index tree, so that repeated files are avoided, and disk space is saved.

Description

technical field [0001] The present disclosure relates to the technical field of computers, and in particular, to a file operation method, device, storage medium and electronic equipment. Background technique [0002] With the rapid development of information technology, people need to process files in multiple file systems, such as local mirror file systems and network file systems. In related technologies, since multiple file systems store and operate data independently, as the number of processed data files increases, more duplicate files will appear, wasting disk space. Contents of the invention [0003] In order to achieve the above purpose, the present disclosure provides a file operation method, device, storage medium and electronic equipment. [0004] In a first aspect, the present disclosure provides a file operation method, including: [0005] Obtain an operation request from the target file system to the target access node; [0006] Judging whether the adapter...
