When I plug an external memory I get a notification, if I choose “open with file manager” I can see all files and folders of memory but it doesn’t appears among devices, in the lower left corner.

You perhaps have the “Removable Devices” section hidden.
Right click on the “Devices” section and from the context menu choose “Show Hidden Places”
This is exactly the problem. Now external memory appears in Dolhpin as soon as I insert it. Thanks.
