I just started with a new I3 MK3S, and copied an .stl file to the sd card, also used slicer to convert to .gcode and copied to sd card. When first starting the printer neither new file is shown on the screen. All files that came with the card are displayed but not either file I copied to it. Checked the sd card on a usb card reader and all files show up including the 2 new files. Why won't the print controller show the new files?

I get a message saying that not all files will be displayed, when I have a lot of files on the SD Card

Stick to basic alphanumerics, a to z and 0 to 9 if you want to be safe.
No there are only 14 files counting the 2 I added.

The same format and charactors all the other files use, and they all print correctly. The second I now see specifies the MK4IS and can understand that now. But the spects on the I3 MK3S says it can use .stl files too. What don't I understand here? I will reslice the cow.stl file again and use the correct printer this time and see what happens. Thanks for your help.

The other thing is the bgcode, that’s a new format called binary gcode. It was introduced by Prusa for their new firmware versions of the mini, mk4 and xl. Older versions of the firmware on those printers don’t know what bode is either. The MK3 based boards have no idea what they are.
You can NOT use files sliced for other printers on your MK3 without having potential problems. Always slice model files for the printer and filament you intend to print them with, in general they are not interchangeable.
