Loading display via tft file

Hello everyone!
I use the NX1060P101 011 display.
When loading via SD card, it gives an error if the size of the tft file is more than 1 kilobyte.
Any file is loaded via USB cable.
Does anyone know what the problem is?
I hope for your help

That is telling you your file is to big. Reason for the size limitation depends on the card and software you are using.
