I get one csv file  with the following  simple structure saved in ANSI format
1,2,3
4,5,6
7,8,9
The total size in my window folder show the size is 30byte , so I try to count it , every data is two byte in ASCII format
so there should be 2 byte * 5 data in 3 rows (including ",")= 30 Bytes but I wonder why that doesn't  include
line-return two byte for every row. The line-return code should be inside of the csv file, otherwise how
can I extract the csv file data from recongizing  every line by line-return, for example, we are using
var dataRows = data.split( "" ); in javascript  to move next  line,  or $line_of_text = fgetcsv($file_handle, 1024) in php.


If it is true, it should be total size= 36 bytes instead of 30 bytes. ? OR for ANSI file, window doesn't count
line-return byte for the final size of the file ?


Please advise.

var dataRows = data.split( "" )

I look into ASCII code table
it specified those key in 2 byte such as 2C(hex)  for ",".

"2c " not two bytes, its one byte.
Byte = 8 bit or 0-255 in decimal, 00-FF in hex/
