    Hi @Richkm ,

    The best practice states that you should always install an application on a separate disk/partition and leave the C-drive for the operating system, and especially if you're using a SQL database, you should preferably have that also on a separate disk/partition.

    Before consider any shrinking, I suggest you have a look at Kevin's SCOM database maintenance article over here:

    (Most should also apply for SCOM 2019)

    Here's also an old TechNet forum thread discussing about this:

    @Richkm , For our environment, I notice there's only one c drive in our environment. And now the disk is full. And we want to shrink the Operations Manager DW.

    Based as I know, if only the Operations Manager DW is not working, most of the SCOM function can still work.

    To shrink OperationsmanagerDW database file size, we can follow the steps in the link below:
    Note: Please ensure backup is done.

    For our situation, we recommend to add another disk and move the SCOM databases to the new disk. This can avoid OS down when the disk out of space because of the SCOM database growing fast. To change the SCOM database to a new drive, here is a link for the reference:

    If the disk is not under our consideration recently, we can try the actions in the following link to reduce the size of our SCOM Data Warehouse size:
    Note: Non-Microsoft link, just for the reference.

    Hope it can help.

    I think that the Shrink unused space on operations manager DW does not affect SCOM but it is not the recommend solution in solving your issue.

    1) If possible, relocate your operations manager database or data warehouse into another server or addition hard disk drive

    2) use Operations Manager 2012 Sizing Helper Tool ( to plan your hard disk space for operations manager database and data warehouse.
