S.D.Card that needs a “Flash”

I need to delete those pesky files that won’t go Away. ls it possible to just buy a new S.D. Card for the Woodwork ? I’m seventy years old and have enough problems designing let alone trying to Reflash something … thanks for your time…

Is this card for file transfering or is it the operating system for something?
If you find the card on your pc you should be able to right click on it and format card.

Good evening,it’s the card that is inside the controller. I’m trying to delete the files that come up on my cnc monitor.not the ones by the trash can,it’s the ones on the other page…there a real pain in the rump!!
