Reference: Manage FTP Server Types
This field captures the maximum number of lines used to display each file. Most FTP servers return one line per file entry. Some, however, return two or more lines per entry. Some return a variable number of lines. Beyond FTP handles this by testing the template against each combination of lines. If the first line satisfies the template, no other lines will be gathered. Otherwise the next piece is added and tested again. The window is moved along the raw data stream until a template match is found or the data is exhausted. When coupled with the OR keyword in the template, this allows dynamic data interpretation.
