How to increase hard disk space on OpManager-Server

Hi everyone,

The free disk space on our server running OpManager, has lately become very full.

Is it possible to remove temporary files or log files in the OpManager program folder? We've got a Windows Server 2008 R2 Machine. I have already looked with the tool "windirstat" at the hard disk allocation and I think that these folders take relatively a lot of space:

C:\Program files (x86) \ManageEngine\OpManager\logs
C:\Program files (x86) \ManageEngine\OpManager\tomcat\logs
C:\Program files (x86) \ManageEngine\OpManager\tomcat6-old\logs

Moreover:

Folders and files in the directory C:\Program files (x86) \ManageEngine\OpManager\Patch

Which of them can be easily cleared without problems?

Thank you for your answers,

best regards,

Erik
