byte

I've a few lines of code within a project, that I can't see the value of...

buffer[i] = (currentByte & 0x7F) | (currentByte & 0x80);

It reads the filebuffer from a file, stored as bytes, and then transfers then to buffer[i] as shown, but I can't understand what the overall purpose is, any ideas?

Thanks
