File Allocation Methods Explained | OS Tutorial for GATE, UGC NET, BCA & CSE

Struggling to understand how files are stored in disk space? In this video, we dive deep into File Allocation Methods in Operating Systems. We break down the different ways data is organized on a disk to ensure efficient storage and retrieval. This tutorial explains the two main categories of file allocation: ✅ Contiguous Allocation: Storing data in a continuous manner and the problems of fragmentation. ✅ Non-Contiguous Allocation: * Linked Allocation: How pointers connect data blocks and the limitations of sequential access. Indexed Allocation: Using index files to point to data blocks for faster access. FAT (File Allocation Table): Understanding the universal index file system.
