On a Windows SBS 2008 server we have Symantec Endpoint Protection Manager installed (version 12.1.671.4971). Also, the Symantec Endpoint Protection client is installed on the server (same version).

The server has a limited amount of diskspace, and they are starting to run out. I've run a scan with TreeSize to see what's taking up all the space and I've noticed this:

C:\ProgramData\Symantec\Symantec Endpoint Protection\12.1.671.4971.105\Data\Definitions\VirusDefs

This folder is taking up 6,2GB and it contains folders like "20130110.024", "20121217.003", etc. etc. There are about 16 of such folders in the VirusDefs folder, which is weird because I've set in the SEPM settings to only keep the last 3.

But, I've also found this folder:

C:\ProgramData\Symantec\Definitions\SymcData\virusdefs32

This folders is about 1,2GB and contains three subfolders like "20130110.005". Since this folder only contains three folders it would seem the settings of SEPM are applied here.

We're getting to my question: Can I safely delete the old definitions folders from the VirusDefs folder? And where could I set the setting to only keep the latest three virus definitons, like in the virusdefs32 folder.
