Why do you want a file system inside a file? The only reason I can
think of to do that is to emulate the file system of another computer,
e.g. a virtual machine.
There are many use-cases. In the context of rsync(1) backups, each file
contains one backup filesystem. If you have seven such files, you can
rotate them daily and one complete backup for each day of the week. If
you set the backup image file permissions correctly, you can easily view
and/or move those files using standard tools. But, one challenge is
finding the "right" file size. Some people use LVM inside the files to
provide additional flexibility.
