By default, the Desktop app, will choose a default location where all your lessons will be downloaded. You can change the location to store at a different location on your computer of external hard drive.
To do so, click on Options > Storage Management.
Here you can view the path where your files are currently stored and [Change] to select a new location.
Note: When selecting a new folder, please be sure to only select/create a folder with alpha/numeric name. Do NOT include any characters or symbols as this will break the Desktop app.
Correct folder name - "TrueFire courses"
Incorrect folder name - "TrueFire/courses" - "TrueFire ~ Courses"
If you have already downloaded files, the Desktop app will automatically move the folders to the new location.
