Colasoft Capsa generates HTTP, email, FTP or DNS log files only when these logs are enabled in the Project Settings - Log page, where you can designate analysis ports, set filters, select log location or customize other options.

The format of log files is: name%year-%month-%day hour.minute.second.log. For example, a log generated on August 18th, 2005 09:25:23 AM with the base file name "http" is shown as http2005-08-18 09.25.23.log.

Logs can be saved to a single file or split files. If you select split files, Colasoft Capsa will automatically split log files by month, day, hour, minute, KB or MB.
