Data Clearing Method Using White List Access Time Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accumulation of temporary files and file directories on terminals over time leads to decreased operation speed and disorganized file browsing, with existing clearing methods only addressing software application usage frequencies without effectively managing files and folders.
Innovation Solution
A data clearing method that scans a data structure with nodes storing latest access times and file information, clearing data if the access time exceeds a threshold and the data is not on a white list, while maintaining system files and folders for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If all accumulated temporary files and file directories are cleared, then storage space is freed and system operation speed is improved, but system stability may be compromised due to deletion of essential files
Solution Approach 1:
The patent applies local quality by differentiating between removable temporary files and protected system files. The white list mechanism assigns different protection statuses to different files based on their importance, allowing aggressive cleaning of unsafe files while maintaining stability of critical system files.
Solution Approach 2:
The white list acts as an intermediary mechanism between the file clearing process and the file system. It mediates the deletion process by filtering which files can be safely removed and which must be preserved, thus resolving the contradiction between cleaning effectiveness and system stability.
2Quantity of substance
If usage frequency-based clearing is used for software applications, then storage space is recovered, but files and folders are not effectively managed
Solution Approach 1:
The patent extends the clearing mechanism from solely software application management to universal file and folder management. The same white list-based clearing logic applies to both applications and files, making the system versatile across different types of data while maintaining storage space recovery.
Data Source
AI summary
The present disclosure relates to a data clearing method, apparatus, and storage medium. The method includes: determining whether a difference between a latest access time of data stored in a currently scanned node in a data structure, and a current time is greater than a predetermined threshold, where the data structure includes a plurality of nodes and each node store a latest access time and file information of respective data to be cleared; if the difference is greater than the predetermined threshold, determining whether the data to be cleared is in a white list; if the data to be cleared corresponding to the currently scanned node is in the white list, continuing to scan a next node; and if the data to be cleared corresponding to the currently scanned node is not in the white list, clearing the data to be cleared corresponding to the currently scanned node.
