Data Storage Directory Structure

EMarketOffer creates two separate directory structures during installation:

• Program files
• Data files

Program Files

During the installation process you can choose where EMarketOffer places its program files (default C:\Program Files\Ellsoft\EMO). This folder contains the EMarketOffer executable and the dlls (dynamic link libraries) required by the program.

Warning! You should not attempt to modify or move the location of any of these files after installation - doing so will cause the program to malfunction.

Data Files

Figure 1 - The Directory Structure

During installation EMarketOffer creates a data directory structure containing the folders to the right:

You can select the location for the data folders during the installation process. For performance reasons it is recommended that the data folder be located on the same computer as the EMarketOffer executable.

The Connection Folder

The information required to connect EMarketOffer to external databases is stored here.

File	Purpose	Comment
<Configuration_Name>.xml Where <Configuration_Name> is the name of a previously created Database Connectivity Configuration.	Stores database connectivity data referred to during program launch	Editing, deleting or moving this file may cause EMarketOffer to malfunction.

Offers

EMarketOffer can load Offers from a database or from file. Offers files in the standard CSV format as provided by the COMIT system can be placed in the Offers folder, which can also be used as a library for user-defined/amended Offers data.

NOTE: This folder is created during installation for convenience; however EMarketOffer can read properly formatted files from any location.

Grid

EMarketOffer uses accurate Transmission System data for analysis of historical periods and as input into Forecast Definitions and Powerflow Cases. Transmission System configuration data downloaded from The EM6 and COMIT information services must be placed in respective sub-folders under this folder. EMarketOffer 'looks for' preferentially for system configuration data in these files during startup.

The Input Data section contains details on each file type.

The Licence Folder

Your customised license file is stored in the License folder.

Warning! This file contains important information about your installation. It is encrypted and you should not attempt to edit this file in any way. The program will fail to startup if the licence file is missing or altered.

The Maps Folder

Data required to support the Mapping function is stored here.
