===== Sewers2 Version Numbers ===== With the release of Sewers2 we are using a version numbering scheme that reflects the date of the version: YYYY.MM.DD So a version of 2020.03.22 means the program was compiled on 22 March 2020. ===== Serial Numbers ===== Serial Numbers are 8 digit numbers built up from the creation date of the design and a tie breaker. The first two digits are the year, the following two the month, then the day, and then a two digit tie breaker where the first design of the day is 01: YYMMDDXX Example: 20022603 = 3rd design for 2020 Feb 26 You might also notice an additional serial number on the side of the file record. This alternate serial number is a year plus sequential number. We add this extra serial number to make filing your records easier. YY - XXXX Example: 20-0034 = 34th design for 2020 ===== Client Codes ===== Client codes are used to make client information independent from the design. That way the same client can be used on many systems. The client code is an 8 character string. The first four characters are the first four letters of the client's last name. The last four characters are a four digit tie breaker. Client codes are generated automatically when you add a new client. ===== Directory Structure ===== All of your Sewers data is saved in one place. By default your data is stored in the "Sewers_Data" folder in your documents folder, but it might be stored in another location if your documents folder is not writable. You can store the "Sewers_Data" folder anywhere that your permissions setting will allow you to write. To find where you data is stored click "About..." in the "Help" menu. Sewers_Data" has the following structure: * Sewers_Data * db - the main database where the systems you design are stored * personas - contains one folder for each persona * plotlans - copies of each plot plan you have created * DesignArchive - PDF's of each of the designs you have printed or saved as PDF's. **YOU SHOULD PERIODICALLY BACKUP YOUR SEWERS DATA FOLDER!**
