Answer:
4 GB
Explanation:
<u>Determine the maximal size of a file </u>
100 direct block address
= 100 * 1024 = 102400
One single indirect block address
= 128 * 1024 = 131072
One double indirect block address
= 128 * 128 * 1024 = 16777216
one triple indirect block address
= 128 * 128 * 128 * 1024 = 2147483648
one quadruple indirect block addresses
= 128 * 128 * 128 * 128 * 1024 = 274877906944
maximal size of the file
= ∑ 102400 + 131072 + 16777216 + 2147483648 + 274877906944
= 4GB
