Using the Program

Multi-Column Support

The program is designed to handle extremely large files in the shortest possible time. Therefore, to avoid spending extra time analyzing the processed data, many functions include the "Multi-Column Support" setting, which allows the user to explicitly specify that the processed list contains multiple columns. By default, this setting is disabled, which means the text file is assumed to contain only one column (email addresses).

If multi-column support is enabled and no explicit column is specified for sorting ("Sort By Column"), sorting is performed by the first column. If sorting by domain ("Sort By Domain") is enabled, it is assumed that the first column contains an email address, where the domain part comes after the @ symbol.

Maximum Line Length

If a line in the input file is longer than the maximum length of 2048 characters, it will be truncated.

Pre-Sorting (Sort First)

Some functions, such as merging mailing lists, require the input files to be sorted in advance. In such cases, the "Sort First" option is available. If you are sure that the files are already sorted in the required order, you can disable this option to save time.
