You can delete files from Ruida controllers using Windows->File List.
Hmm… I guess I’ve only ever sent one file or that one must have gotten overwritten as there was only one on it 
Thanks for the Info! =)
If you use the “Start” button in LightBurn, the same file is sent and overwritten. If you use “Send” then files will accumulate in that list.
Ruida controllers have been known to start behaving erratically when storage gets low so I’d advise not letting your controller fill-up.
