Size of survey on local server

We have installed survey solutions on our local server. Can you please advise how to determine the size that the created HQ application occupies on the server including data collected etc? Do we simply right click on the the HQ app folder and check the size in Properties>

Thanks

There are two parts of the data storage - most of data are stored in the postgresql database so you would want to check the size of %PGDATA% folder (if you installed following default settings then it should be c:\program files\postgresql\pg[version]\data folder). If have a picture question in your questionnaire then also look at the c:\program files\survey solutions\site_data\images folder.
