3. Security: The file system provides permission management functions, which can limit the access permissions of different users and protect the security of files.

4. Reliability: The file system is fault-tolerant and can recover files when hardware failure or data corruption occurs.

However, the file system also has some disadvantages:

1. Performance issues: For the processing of large files or a large number of files, the file system may have performance issues bottleneck.

2. Management complexity: As the amount of data grows, the management complexity of the file system will also increase, requiring more maintenance and management costs.

3. Compatibility issues: Different operating systems and file system formats may have compatibility issues, resulting in possible problems with cross-platform file access and management.

4. Data redundancy: In the file system, there may be data redundancy, that is, too much duplicate data is stored.

In general, the advantages and disadvantages of file systems depend on specific application scenarios and requirements. For most users, the main advantage of the file system is that it makes the storage and management of files more convenient, orderly and secure.
