When you don't have a computer at hand and want to retrieve a project from an HMI, you can use a USB flash drive to upload it.
First, create a new folder on the flash drive and name it 'upload'. Then, insert this USB into the HMI, and it will ask if you want to upload the project. Choose to confirm and wait for the process to complete.
Subsequently, in the software, select the decompile function to obtain the project content.
