Arduino Mega 2560
TFT LCD Mega Shield V2.2

I want to read/write "file.txt" from SD card (SD card on card socket of 3.2" TFT LCD )
I saw some topic and forum, but i not found the way to do it, help me  :(

You need to check the relevant data sheets, and be more forthcoming on your code and equipment.

My 400x240 has the SD on the shield, and I had to bridge a pair of solder pads in order to use it. I understand yours is on the display but you may have to do a similar trick somewhere, most likely on the shield.  I also had to change the chip select from the usual 4 to 53.  This is in addition to the usual command

pinMode(53, OUTPUT);

required on the Mega.  I believe both commands relevant to pin53 are required.  This applies to the standard SD CardInfo example.
