When image assets are uploaded to DF Studio, JPEG previews of various sizes are generated for display in the web browser. These files are referred to in DF Studio as Project Storage. The original uploaded files are put into Active Storage where they can be preserved as a backup or delivered to clients.
Files in Active Storage may be moved to Cold Storage or deleted to reduce the amount of storage used without affecting the DF Studio previews, thus continuing to enable all of DF Studio’s features, with the exception of downloading the original file.
