purge unused dirs

[maumar]

sorry if this was already asked for, but searching for purge in the first page i have found anything related.

So, my question is:
after each upgrade i find a bunch of dir renamed, like postfix and jdk

drwxr-xr-x     4 root   root    4096 Apr 13  2008 postfix-2.2.9
drwxr-xr-x     3 root   root    4096 Apr 13  2008 postfix-2.4.3.3
drwxr-xr-x     3 root   root    4096 Apr 13  2008 postfix-2.4.3.3z
drwxr-xr-x     4 root   root    4096 Jun  7  2008 postfix-2.4.3.4z
drwxr-xr-x     3 root   root    4096 Jun  2 21:00 postfix-2.4.7.5z
drwxr-xr-x     3 root   root    4096 Aug 22 19:59 postfix-2.6.5.2z
drwxr-xr-x     6 root   root    4096 Aug 22 20:00 postfix-2.6.6.2z

rwxr-xr-x     3 root   root    4096 Sep  6  2006 jdk1.5.0_06
drwxr-xr-x     3 root   root    4096 Sep 27  2006 jdk1.5.0_07
drwxr-xr-x     3 root   root    4096 Oct 12  2007 jdk1.5.0_08

drwxr-xr-x     3 root   root    4096 Jul 12  2009 jdk1.5.0_17
drwxr-xr-x     3 root   root    4096 Oct  4  2009 jdk1.5.0_19
drwxr-xr-x     3 root   root    4096 Jun  2 21:01 jdk1.5.0_20
drwxr-xr-x     3 root   root    4096 Apr 13  2008 jdk1.6.0_02
drwxr-xr-x     3 root   root    4096 Jun  7  2008 jdk1.6.0_04
drwxr-xr-x     8 root   root    4096 Aug 22 19:59 jdk1.6.0_16

can i safely wipe the older ones?
