# Directories

Exivity uses two main disk directories when it's installed. One to store the user data and one to store the software files. These directories are called the **home** and **program** directories, respectively.

On the system where Exivity is installed, the following environmental variables contain a absolute path reference to these directories: `EXIVITY_HOME_DIRECTORY` and `EXIVITY_PROGRAM_DIRECTORY`.

## Home directory

The home directory should preferably be located on a dedicated volume i.e. `D:\exivity\home` and it is recommended that it be located on an SSD drive.

## Program directory

The main program directory as it should be installed by the Exivity installer:
