Journaling is a feature that helps maintain the integrity of the filesystem by keeping a record of changes not yet committed to the main file system. This feature is supported by various filesystems, but not all.
Option A: NTFSNTFS (New Technology File System) is a filesystem used by Windows that supports journaling. This makes it resilient to corruption from unexpected shutdowns or crashes by keeping a log of file changes.
Option B: exFATexFAT (Extended File Allocation Table) does not support journaling. It is optimized for flash drives and large files but lacks advanced features like journaling.
Option C: HFSHFS (Hierarchical File System) is an older filesystem used by Apple. HFS+ (also known as Mac OS Extended) supports journaling, but HFS itself does not.
Option D: ext2ext2 (Second Extended File System) is a filesystem for Linux that does not support journaling. Its successor, ext3, introduced journaling.
