The C:\ManageEngine\DesktopCentral_Server folder on my server has grown to about 9GB.

There's some subfolders and single files there related to patches that have been applied to the Desktop Central application itself, not to be confused with "patch management" for applying patches to client machines. These are new releases of Desktop Central that have been applied via the .ppm files.

I have around 430MB of .ppm's located under the Patch subfolder, as well as various other subfolders named with each version. 

I've attached a screenshot here so you can see what I mean.

Can any of this stuff be deleted? Is there a "correct" way to clean these up through Desktop Central?
