Dear Aaron Morton
I'm Hiroshi. Thank you for the reply.
$KS/$CF/snapshots directory namely :
Under C:\var\lib\cassandra\data\MyKeyspace\testcf1
dir command execution:
2013/05/09 14:04 <DIR> .
2013/05/09 14:04 <DIR> ..
0 File(s) 0 bytes
2 Dir(s) 139,587,530,752 bytes free
snapshot was not generated.
It is a repeated question (I am sorry).
When "drop column family" is executed irrespective of the existence of
generation of Snapshot, $KS/$CF/ directory certainly remains.
It is a meaning?

A snapshot is taken when a truncate or drop command is run. You should see a
$KS/$CF/snapshots directory.
