File Management System Thumbnail Generation Unused File Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing systems for remote work, particularly those using cloud services, lack efficient methods to manage and identify unused files, especially image files, which can lead to storage inefficiencies and increased costs.
Innovation Solution
An information processing system that generates screen information for displaying file lists, including file names and thumbnail images for image files, and detects unused files based on usage status, allowing administrators to easily identify and manage unused files by storing logs and thumbnail images alongside uploaded files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cloud services store all uploaded files including image files for remote work, then file accessibility and collaboration are improved, but storage costs and resource consumption increase due to accumulation of unused files
Solution Approach 1:
The system performs preliminary actions by generating thumbnail images and detecting unused files before they consume excessive storage resources. The thumbnail generation occurs immediately upon file upload, and unused file detection is performed periodically, allowing proactive management of storage resources while maintaining file accessibility.
Solution Approach 2:
The system creates a simplified copy (thumbnail) of the original image file that occupies minimal storage space while preserving the essential visual information needed for identification and management. This thumbnail copy enables administrators to view and manage files without requiring the full-resolution original, significantly reducing storage requirements.
2Quantity of substance
If administrators manually review files to identify unused ones, then storage optimization can be achieved, but time consumption and operational complexity increase
Solution Approach 1:
The system performs self-service by automatically detecting unused files through analysis of access logs and usage patterns without requiring administrator intervention. The system autonomously identifies files that have not been accessed within a predetermined time period and presents them for potential deletion, eliminating manual review processes and associated time consumption.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring file access patterns and usage status, then using this information to automatically identify and flag unused files. This feedback loop enables the system to adaptively manage storage resources based on actual usage data, optimizing storage efficiency without manual intervention.
3Ease of operation
If the system displays detailed file information including thumbnails for all files, then file identification and management become easier, but data transmission volume and processing load increase
Solution Approach 1:
The system extracts only the essential visual information needed for file identification by generating and displaying thumbnails, while separating this from the full-resolution original files. The thumbnail extraction provides sufficient information for administrators to identify and manage files without transmitting or storing the complete original image data, significantly reducing data transmission requirements.
Solution Approach 2:
The system segments file information into two distinct components: small thumbnail images for display and management purposes, and full-resolution original files for actual use. This segmentation allows the system to transmit and process only the necessary thumbnail data for administrative tasks, while keeping the larger original files stored separately for on-demand access.

AI summary
An information processing apparatus, an information processing system, an information processing method, and a non-transitory recording medium. The information processing apparatus receives a plurality of files, generates screen information for displaying a first list screen on a display, the first list screen presenting, for each of the plurality of files, a name and a time of last use of the file, and further presenting a thumbnail image of at least one file of the plurality of files in a case the at least one file is an image file, stores in one or more memories, the plurality of files and the thumbnail image of the at least one file being the image file, and transmits the screen information of the first list screen in response to a request.
