Folders Exist After Installing Exchange Server 2013

Hi,

We installed Exchange Server 2013 SP1 a while ago and noticed two directories were created:

D:\MonitoringDiagnosticLogs\MSExchangeHMHost (Contains a file called MSExchangeHMHost20141231-1)

and

D:\TransportRoles\Logs\SyncHealth\Hub

I also noticed the second folder is addressed in Cumulative Update 5.

I have the following questions:

1. Does applying CU5 remove the second directory? If not, is it safe for me to delete this directory?

2. What about the first directory? How do I get rid of that? Is it safe for me to delete it?

3. If I cannot get rid of the two directories is it safe for me to create a new partition, move the directories to it, and mark it as D:\ so the path remains the same?

Thanks for the help!
