[redsolution-mx]

Actual behaviour

-la app en Android se sale al cargar un directorio con gran cantidad de fotos en el servidor

Expected behaviour

-la app debería de cargar las fotos o directorios 1 en 1 o mantener un índice para cargar más rápido el contenido y no salirse y cerrarse por tiempo

Steps to reproduce

1. La app se conecta al servidor
2. Muestra el directorio principal y si se ingresa a un subdirectorio carga todo el contenido
3. Debe mantener la conexión hasta que se cargue todo el contenido

I was a little bit curious what the users has written and used Google translator for the translation:

Actual behaviour If you try to load a directory from the server which contains many files, the app crashes.

Expected behaviour The app should load all files or directories 1:1 without crashing. It should also keep an index of the direcory entries to speed-up the load process (... and prevent reading the whole directory content again and again over a bad connection)

Steps to reproduce

1. Connect the app to the server
2. The home directory is shown and if you choose a sub-directory you have to wait until the whole content of it has been loaded.

3. You have to stay connected until the whole directory content has been loaded.

   (My understanding: @redsolution-mx wants to say that it isn't possible to read the directory content in chunks yet)
