Formatting File having big single line into 95 Char Per Line

Hi All,

I have 4 big files which contains one big line containing formatted character records, I need to format each file in such way that each File will have 95 Characters per line. Last line of each file will have newline character at end.

Before:-
File Name:- File1.dat
Code:
102 121340560 1210001341210300400A094101ABCDEFG ABCDEFGH SEDABCD ABCDIFARION RFTPERSR        1234ABCDCARPABCDEF                   0366130207ASDFGYHUIO11011212110130610710034042404246222910750809020101142       0000026950329075001      ABCRFTYU DERTF           0071003402508271820000000100291075080000000000000000000269500366

After:-
Code:
102 121340560 1210001341210300400A094101ABCDEFG ABCDEFGH SEDABCD ABCDIFARION RFTPERSR        
1234ABCDCARPABCDEF                   0366130207ASDFGYHUIO110112121101306107100340424042462229
10750809020101142       0000026950329075001      ABCRFTYU DERTF           0071003402508271820
000000100291075080000000000000000000269500366

Similar remaining file will be formatted in same fashion.

I ma sorry but when I execute this command I get either file not found or 0+0 records in & o bytes copied.

Code:
dd if=<File1.dat> of=<File1Final.dat> cbs=95 conv=unblock

Here File1 is the file name
File1Final.dat trying to copy finalize contents to new file.
Thanks,
Lance

Remove the "<>" around the file names

Thanks vbe, scottaazz & Scrutinizer. All your solution worked.
Can you guys please tell me what I need to do in order to add new line after only last line in the file?

Here are the command which worked:-
Code:
fold -w95 fileName

OR
Code:
dd if=FileName.dat of=NewFile.dat cbs=95 conv=unblock

Thanks,
Lance

dd's unblock conversion yields variable length records/lines. If, as you say, the result must consist of 95 character lines, you cannot use that dd approach, because it will strip trailing space characters from a 95 character block and leave something shorter.
