If you want to conserve space on your system drive, you can save an instrument's library folder (STEAM for Omnisphere, Keyscape, Trilian and SAGE for StylusRMX) to a secondary or external drive instead.
Before installing, it is import to determine the current format of your hard drive.
For Format Guidelines, see here.
Once you have confirmed that your drive is properly formatted, proceed with these steps:
1. Create a new folder called “Spectrasonics Libraries” on your external/secondary drive
2. Run the appropriate installer for your instrument/operating system
3. When you're asked to Select Folder for Data, select Browse, and select the “Spectrasonics Libraries” folder you created from step #1 .png)
4. Click continue until the installation is complete
Note: If there is a pre-existing library folder or folder alias/shortcut at the default location, you will not be able to select a new location at Preparation. You will either need to move the existing library folder or change the location linked via the alias/shortcut, as detailed here.
