NotI am not sure where to ask this question,so so perhaps it is physical limitation.
I have 8Gba 8 GB flash micro SD memory card. When I copy any file size of up to few gigabytes, copying happens normally. But if I am trying to copy file over 4Gb4 GB file, then the system telltells me like insufficient memory on card, although 8Gb8 GB is available. So perhaps only 32 bit address is used for keeping size of file in micro SD card, or is my micro SD defective?
