Efficient Space Allocation: Ext4 uses techniques like extent-based storage and delayed allocation to minimize fragmentation and improve disk space utilization. This helps in maintaining consistent performance over time. Backward Compatibility: Ext4 offers backward compatibility with Ext3 and Ext2 file system...
