MediaBrowser Temp Files Too Much Disk Space

hi there. i recently started using mediabrowser. the hdd for my OS is rather small, and i only have about 50GB free, but ive noticed 20GB+ of free space disappearing since using media browser. ive only played files under 10GB, so im not sure why over 20GB would be unavailable due to serviio.
how is serviio software managing temp files that negatively impact disk space? restarting frees up the disk space, but ideally it wouldnt take up so much disk space at all. perhaps temp files need to be deleted immediately after streaming stops, or there should be a way to limit how much disk space youre willing to give up to serviio transcoding temp files?
or perhaps the option to choose where the temp files are placed? my library is comprised of content on external hdds, but mediabrowser playback hogs my internal hdd, which i dont use for videos at all.
