The easiest way to copy files on the machine is using an SFTP browser like FileZilla.
You will find a volume mounted at
/assets. That’s the space to put all your files. It contains five folders:
||put your app here|
||put your images, videos, etc. here|
||screenshots will be saved here|
||log files, well if your app saves ’em here|
||app bundles that are locally available to install through the settings server|
