File Rotation Detection via Identification Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing file management systems struggle to detect and manage file migration and rotation accurately, especially when file names change, leading to issues during copying processes and inadequate management of file groups with different names.
Innovation Solution
A file management method and device that create rotation groups based on changes in file names, store relevant information, and compare file identification data to detect rotation and ensure proper copying by retrying the process when rotation occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If file migration detection is limited to the same file name, then file management is simplified, but file rotation cannot be detected when file names change
Solution Approach 1:
The patent introduces an intermediary mechanism (file identification information management unit and rotation group management unit) that stores and manages file identification information independently of file names. This intermediary layer allows the system to track file rotations by comparing stored identification information with current file information, thereby detecting file rotations even when file names change, while maintaining simplified file management operations.
2Adaptability or versatility
If applicable period information is included in respective files for generation management, then master file data in multiple generations is managed, but some files may not be managed due to lack of this information
Solution Approach 1:
The patent extracts the file identification information management from the individual file level and places it at the system level through the file identification information management unit. Instead of requiring each file to contain applicable period information, the system maintains a centralized registry of file identification information that can track and manage all files in the rotation group, ensuring complete coverage without modifying individual files.
3Ease of operation
If file groups with different file names are managed as separate groups, then each group is managed independently, but file rotation across different names cannot be detected
Solution Approach 1:
The patent merges the management of files with different names into a unified rotation group by introducing a rotation group management unit. This unit consolidates file identification information from files with different names into a single management structure, allowing the system to detect rotations across name boundaries while maintaining the operational independence of individual file groups through the standardized identification information interface.

AI summary
A file management method includes creating a rotation group by grouping a file group in which the generations of the files are managed by changes in the file names, and storing information of the rotation group in a rotation group management unit; acquiring file identification information of the files belonging to the rotation group from the file group according to the information of the rotation group, and storing the file identification information in a file identification information management unit; and acquiring file identification information of the rotation group from the file identification information management unit, further acquiring file identification information of the files belonging to the rotation group from the file group according to the information of the rotation group, and comparing the acquired pieces of file identification information.
