Hello,
for my program to be fast, I use some unformatted file.
My question is, If I bzip those unformatted file, will the data change?

Do you mean bzip2 or gzip?

If so, the answer is yes, of course the data changes, but when you
decompress the file you get the original back. Both gzip and bzip2
are loss-less compression programs.
