How Can I Remove The Line Feed/carriage Return In The Last Line Of The Exported Text File ?

Hi,
for some AP issue, the file I upload must be without the line feed/carriage return in the last line.
for example:

original fixed-length file (exported from SSIS)
line NO DATA
1 AA123456 50 60
2 BB123456 30 40
3 CC123456 80 90
4 <-- with line feed/carriage return in the last line

The file format that AP request. The file only has 3 records, so it should end in the third line.
line NO DATA
1 AA123456 50 60
2 BB123456 30 40
3 CC123456 80 90

Should I use script component to do it ? I am new for VB . Anyone would help me ?

Thank you all.
