How do I install a RAM drive on an existing MetaDefender Core installation?

When installing MetaDefender Core for the first time, you will be given the option to install the RAM drive which will automatically configure itself for your installation.

If you wish to set up and configure the RAM drive for Metascan servers that are already running without reinstalling MetaDefender Core, please follow the steps below:

  1. Download the RAMdrive ZIP file and extract it to a permanent location.

  2. Open the folder that corresponds to your OS (x32 or x64). For most customers, this will be the x64 folder.

  3. Run ramdrv_install.exe as an administrator. Note that this might take some time and during the installation you must accept the certificate for the driver.

  4. Check your computer for the O: drive. If this drive is not present, restart the machine.

  5. Open Windows Device Manager.

  6. Under RAM Drive, double-click OPSWAT Secure RAM Disk.
    Note: This menu allows you to configure the size of the RAM drive. Please read this article to understand how the RAM drive constraints should be set on your system.

  7. Allocate as much capacity as you feel comfortable. The larger the files you plan to scan, the larger you will want the RAM drive to be.
    Note: MetaDefender Core will not allow you to scan archives larger than half the available temporary storage. To get around this limitation, we recommend setting a secondary temporary directory.

  8. Open the MetaDefender Core Management Console and go to Workflow > Scan Configuration.

  9. Set the Secondary Temp Directory to the current value of the Primary Temp Directory. Typically, this is C:\Windows\TEMP\.

  10. Set the Primary Temp Directory to O:\.

  11. In the Workflow tab, navigate to Archive Handling and ensure that the current archive settings are adequate as they may have been lowered during the previous steps.

  12. If you run a local antivirus with real-time protection, add an exclusion for the O: drive.
