Why bad advice? Java itself stores the JDK there. On my PC
c:\> for %i in (java.exe) do @echo. %~$PATH:i
results in C:\Program Files\Java (x86)\Common Files\Oracle\Java\javapath\javac.exe
This folder is more protected as it belongs to the adm group.
Placing executables on other HD’s normally used for static data storage can (depending on settings) get them out of the sleep mode.
