Hi,
To save your project, follow these steps: click on the "File" tab located at the top left corner of the screen, then select "Save Project As" from the dropdown menu. A new window will appear, allowing you to choose the file format and select the desired location on your computer for saving the file. If you face difficulty in locating the file later on, opt for saving it to your Desktop, as this location is easily accessible. Once you have selected the appropriate settings, simply click "Save" to finalize the process.
