At the FP5 the app files doesn’t look like this.
The best to check if the SD-card is formatted as externel storage is:
Go to the app Settings
Go to Storage
Tap on ‘This device’ and change it to ***SD card ( *** name of the brand of your SD card, mine is Samsung)
Tap on the hamburger menu in the right upper corner
In the pop-up you will see
Rename
Eject
Format
If you see this, then your SD-card is set as external storage
