java - Can I delete the old folders after updating JDK -

windows 8.1, jdk 1.8.0_25;

everytime update jdk, creates new folder followed version number in installation path. after several times, there're 4 of them, each takes more 300mb disk space. what's within seems same except version.

i wanna know, can delete these old folders after updating ？

now installation path looks this:(can't post image, lack of reputation)

c:\program files\java

- jdk1.8.0_05 2014/7/5 - jdk1.8.0_11 2014/7/23 - jdk1.8.0_20 2014/9/1 - jdk1.8.0_25 2014/10/19 - jre1.8.0_20 2014/10/19 - jre1.8.0_25 2014/10/19

yes can delete except - jdk1.8.0_25 2014/10/19 , - jre1.8.0_25 2014/10/19.

and don't forget add together - jdk1.8.0_25/bin path variable.
