👉 Msgid computing is a method used in Unix-like operating systems to manage and compute message IDs (MGs) for files and directories. When a file is created, its MGs are assigned sequentially, but these MGs are not directly used for file operations. Instead, the system uses a hash function to generate a unique identifier (MG) for each file or directory, which is then stored in the Msgid file. This file acts as a lookup table, allowing the system to quickly determine the location of files based on their MGs without needing to scan the entire directory tree. This approach significantly speeds up file operations like listing, searching, and deleting files by reducing the computational overhead associated with directory traversal. Msgid computing is crucial for efficient file management in large and dynamic file systems.
