Storing inc file

At the same location, you can also see a file with same file name but with txt location. This txt file contain only hexadecimal value but with "0x" prefix. I suspect that the data in inc file and txt file are same. I don't even know, what these sromTable mean.

Actually, I have once converted all values in txt file to hexadecimal with "0x" prefix and stored into PROGMEM as an array. But, somehow it didn't work or I don't know, what actually happened. Space limitation (whole data is just 1986 byte, should be a problem for Arduino's 32KB flash,right)?
