Ext3 users - Mar 2008 - Filefrag

hi
I have a virtualbox image of ubuntu hardy. I did filefrag and i got this


hardy.vdi: 73 extents found, perfection would be 69 extents


Why does it say perfection would be 69 extents. Shouldnt it be 1 extent?

If your blocksize is 4k, there are 32k blocks in a group, and therefore 
about 128MB per group. So, your file size must be slightly less than 69 
* 128MB, correct?

Not if it's sparse.  As your fs image almost certainly is.
