I would have expected the maximum file size to be a number of blocks, which makes it seem strange that doubling the block size multiplies max file size by 16. > Ext* started as a UFS "clone" and UFS filesize is limited to 2**63 while > UFS filesystem size is limited to 1 TB. Just for ease of comparison, 16GB = 2**34 bytes = 2**24 1k blocks. 1TB = 2**40 bytes. > That is much more than you claim for Ext3 I'm not doing any claiming, since I'm not an expert on the subject.
