Thanks for the clarification. On ext4,I believe an extent can address upto
128MB. So I assume, for a file of size 50MB ,there is possibility this will
be stored contiguously. Is that correct assumption? and If we mounted ext3
as ext4, will the inode become extent based rather than the old
direct/indirect block accessing method?
