File Manager

The File Manager is a software component within the Storage Manager system, responsible for managing the lifecycle of digital files. Its functions include creation, storage, retrieval, organization, version control, access permissions, and deletion. It provides the interface and logic for users and applications to interact with stored data files while maintaining data integrity and security. Operating as part of a storage infrastructure, the File Manager maintains a file system index or database that tracks file metadata such as name, location, size, type, permissions, and creation/modification dates. It processes user and application requests through APIs or interfaces, performs file operations (read, write, copy, move, delete), enforces access controls, manages storage allocation, and maintains file organization structures like folders, directories, and tags. Typical reference parameters for this component include a maximum number of files up to 1, 000, 000, a maximum file size of 10 GB, transfer rates ranging from 100 to 1000 MB/s, access latency between 0.1 and 5 ms, support for 10 to 500 concurrent users, storage capacity from 1 to 100 TB, data integrity of 99.999% (referenced to ISO/IEC 27001), role-based access control (RBAC) per ISO/IEC 27001, AES-256 encryption per FIPS 197, logging capability of 10, 000 events per second, an API rate limit of 1000 requests per second. These values are directory references and must be verified for the specific model and application with the legal manufacturer or supplier. Standards such as ISO/IEC 27001 and FIPS 197 are listed as procurement or verification references, not as proof of certification or compliance. The File Manager is a software component; its material is software code. For selection, consider the required file count, file sizes, transfer rates, latency, concurrent users, environmental conditions, storage capacity, and security features. Verification questions should address the actual performance under expected workloads, integration with existing storage systems, and compliance with relevant standards. Maintenance signals include performance degradation when approaching limits, such as the maximum number of files or API rate limit.

The File Manager operates by maintaining a file system index or database that tracks file metadata (name, location, size, type, permissions, creation/modification dates). It processes user/application requests through APIs or interfaces, performs file operations (read/write/copy/move/delete), enforces access controls, manages storage allocation, and maintains file organization structures (folders, directories, tags).
