Conversion between different block size filesystems
Hi,
this is for the first time I am using this forum.
I have one question:
When i transfer one file/directory from a Unix system,having file block size of 1024 bytes, to another Unix system ,having file block size of 512 bytes what difference can it cause in terms of file size?
When i checked using (du -sk) the values were different on different systems. what can be the probable cause for it???
