What types of file systems have you used in your practice and what difficulties have you faced when using them?

The following types of file systems are commonly used in practice:

• ext4 (Linux) — stable, supports large files and volumes. Difficulties: may require fsck check after improper shutdown.
• NTFS (Windows) — supports permissions, encryption. Difficulties: limited support in Linux, possible permission issues.
• FAT32 — simple, compatible with various OS. Difficulties: file size limited to 4 GB.
• XFS — high-performance, suitable for large files. Difficulties: more complex recovery after failures.

The main challenges when working with file systems are:

• managing permissions,
• recovery after failures,
• size limitations for files and volumes,
• compatibility between different OSes.
