Server C:\ always 5% free

Server C:\ always 5% free

Hi there,

We have 3 ManageEngine products installed and configured on our server (Windows Server 2008 R2 Standard):
  • ServiceDesk Plus build 9041
  • OpManager Build 11400
  • ADSelfService Plus Build 5206
We got our hard disk (C:\) full before so we increased the space.
But no matter how much we put in, there's always only 5% free space in C:\

Is there a settings in any of those 3 products that similar to "keep logs until disk free space is 5%"?

Thank you.
