Command Line Interface (CLI)

Since version 5.6.0, Primo Ramdisk includes a command line interface that provides flexible, scriptable access to essential Primo Ramdisk operations from the command shell.

Primo Ramdisk command line tool, rxprd.exe, is installed in the folder where Primo Ramdisk is installed (for example, C:\Program Files\Primo Ramdisk Professional Edition). For convenience, set your PATH environment variable to include this directory.

The command line tool requires Administrative privileges. On Windows Vista or newer operating systems that have UAC enabled, run it from a Command Prompt window that is launched by performing the following actions:

  • Right-click a Command Prompt shortcut.
  • Click Run As Administrator.

Command Line Syntax

rxprd <command> [<option>...]

<command>    Specifies a Primo Ramdisk command (see command list below).
<option>...  One or more options that modify a command.

The following conventions are used in the command line tool:

  • Expressions surrounded by angle brackets (<>) are required.
  • Expressions surrounded by square brackets ([]) are optional.
  • Commands are case insensitive, but options are case sensitive.
