Key points
  • Choose the file
  • Choose "Size (KB)"
  • Save the ZIP

In Merge and Split Text Files, text is split by line at roughly the size (KB) you set.

Steps

  1. Choose the file
  2. Under "Split" choose "Size (KB)"
  3. Enter the KB per file and save
A very long single line can make a file larger than the setting.
