  • Thread-topic: Understanding sparse-files

Hello list,

After reading a lot of docu, i am confused.

What exactly is the advantage of sparse-files against "normal" files
with fixed length?

First i thought this is something like an auto-increasing file. But if i
take a 2GB partition and add two sparse-files with 1GB each, i can't add
an additional one, the disk is full?

So what about this mystic advantage? Is it only the faster creation of
that file with dd, because it is not completely filled?
That's all?

Please enlighten me ;)

Kind regards, Florian
