Can you guys please tell me what I need to do in order to add new line after only last line in the file?

Do you mean like this?
Code:
{ fold -w95 infile; echo; } > outfile

Yes I saw this.
DD nevers keeps length 95 per line for some lines.

Even
Code:
{ fold -w95 infile; echo; } > outfile

works till second last line. Last line do not have 95 characters.
How we can make sure last line will also have 95 Characters.

You could try:
Code:
oldIFS=$IFS
IFS="
"
printf "%-95s\n" $(fold -w95 infile1824)
IFS=$oldIFS

If fold is used, and if the input text may contain tabs (or backspace characters), if those bytes should not be treated specially (count as 1 byte instead of modifying fold's width counter), the -b option should be used.

Here's a defensive pipeline:
Code:
od -An -tu1 < file |
tr -cs 0-9 '[\n*]' |
awk 'length {printf "%c%s", $0+0, (++i%w ? "" : "\n")} END {if (i%w) {while (i++%w) printf " "; printf "\n"}}' w=95
