 25.   Do note that you will need to open the **LearnCOBOL** folder every time you connect to the system, repeating step 5 to 7. To enable your connection profile to be accessible anywhere on your machine, you will need to move your configuration files (i.e. `zowe.config.json` and `zowe.schema.json`) from the LearnCOBOL folder to the Zowe global location. By default this is `C:\Users\%USERNAME%\.zowe` for Windows or `~/.zowe` for Linux and macOS.
