I tried this software to split couple of files by line. But the splited files lost couples of lines. Can you feature this out? I do appreciate it if you could tell which lines are lost.

Thanks!

Yes, I did that with adding header to each file chunk set and I were using the UI on a CSV file.

The steps as following,

1. Locate the file and select the Type of File for CSV
2. Select the file I want to split
3. Select the Output Directory, different from the File to Process
4. Click on By lines
5. Fill out 150 for Lines Per File
6. Check on Include Header in Each File Chunk
7. Click the button of Process.

I sorry for some reason I can't provide the file for you. But if you do need it, I will make up one.

Thanks!
