send 32 and then the next 32 and next ...

You can send more than 32 bytes in ONE GO by changing the buffer size in the Wire.h Library. Note that I2C is a byte oriented protocol; it always sends one byte in one transmission frame.

Are there other alternatives? How can I send and receive data(.zip or .rar) between two computers through arduino?

use computer networks to transmit data between computers, not Arduino.

For security, I don't want to share data over the network. That's why I chose arduino. There was no other way? Can't send data over Arduino?

you can connect two computer with a serial cable, USB cable, RS485 adapters, you can even connect two computers directly with an Ethernet cable.

Encrypt your .zip/.rar file and send it using commercial network.

Put the data on a thumb drive and carry it from one computer to another.

Most Arduinos have no file storage capability.
