Yes. Install the Filestar CLI with npm install -g filestar and your agent can run filestarcli -i file.dat -c "play" on your computer, so your files stay on it.
A game's movie file: an ordinary ASF/WMV video whose first 12 header bytes were overwritten by the game's own wrapper (eight zero bytes and the whole file size), leaving every other ASF structure intact. Filestar restores the missing header bytes and converts the video.
