Internal storage sd read in laptop: where are the files?

I am trying to read in a laptop my micro sd card (which was used as internal storage), through a SD card adapter. Goal is to access to my pictures.

On the laptop (using Linux), I see some folders, but none of them contains the pictures. Why am I not able ot access the files themselves? Is there some encryption going on?

The micro sd structure looks like this on Ubuntu:

 ── Android

│   ├── data

│   │   ├── com.android.vending

│   │   │   └── files

│   │   ├── com.google.android.apps.docs

│   │   │   └── cache

│   │   ├── com.google.android.music

│   │   │   └── files

│   │   ├── com.motorola.MotGallery2

│   │   │   └── cache

│   │   └── com.skype.raider

│   │  
  └── cache

│   └── media

│  
  └── com.motorola.MotGallery2

└── LOST.DIR

Thanks!!
