Ext3 is a linux filesystem and used by most of the linux systems. This article shows and example ext3 image usage situation.
we will create and use 20MB ext3 image. 1024×20480 bytes.
first we create an empty file with dd block size 1024
dd if=/dev/zero of=disk1.image bs=1024 count=20480
then we format that image
mkfs.ext3 -F -b 1024 disk1.image 20480
this will give an empty filesystem whose type is ext3.
