Indexed file allocation:
In Indexed file allocation, If a file requires n blocks then n+1 blocks are used where the first block contains index information(pointers to data blocks).
In Indexed file allocation, If a file requires n blocks then n+1 blocks are used where the first block contains index information(pointers to data blocks).
- The Indexed file allocation table contains a separate one-level index for each file.
- The index has one entry for each portion allocated to the file.
- The file allocation table contains the block number for the index.
Hence the correct answer is Indexed file allocation.

Understanding Indexed File Allocation
The scenario described involves utilizing n+1 blocks when a file requires n blocks, indicating that one additional block is used for storing index information. This directly points to the Indexed File Allocation method.
Key Characteristics of Indexed File Allocation:
- Index Block Usage: In indexed file allocation, one block is dedicated to storing the index of the file. This index contains pointers to the actual data blocks where the file's contents are stored.
- Direct Access: The presence of an index block allows for direct access to the file's data blocks, enabling efficient retrieval and modification of data.
- Flexibility: It provides flexibility in managing file sizes, as the index can be easily updated when blocks are added or removed.
- Reduced Fragmentation: Unlike contiguous allocation, indexed allocation can help reduce external fragmentation since file blocks can be non-contiguous.
Comparison with Other Methods:
- Contiguous File Allocation: This method requires all blocks to be allocated in a contiguous manner, without the need for an index block.
- Linked File Allocation: In this method, each block contains a pointer to the next block, and does not use an index block.
- Chained File Allocation: Similar to linked allocation, but focuses on a chain of blocks rather than an index.
Conclusion:
Given the requirement of using n+1 blocks, with the first block storing index information, the correct answer is indeed option 'D' - Indexed file allocation. This method efficiently manages files by organizing data block pointers, allowing for quick access and modification while minimizing fragmentation.
