What difficulties have you encountered when working with file systems?

When working with file systems, I often encountered the following challenges:

• Access rights and security: incorrect permissions can prevent reading or writing files.
• File locking issues: simultaneous access by multiple processes to a single file can cause conflicts.
• Size and quantity limitations: some file systems have limits, which is important to consider when storing large data.
• Performance issues with many small files: operations can slow down.
• Cross-platform compatibility: different OSes may handle paths and characters in file names differently.
• Input-output error handling: for example, when disconnecting external media or network drives.

In practice, it is important to consider these points and use correct methods for working with files, as well as log errors for diagnostics.
