There are many WLAN routers currently available which have a USB port to connect external HDDs. These are than easily available on Windows machines directly in Windows Explorer, they look like common network drives.
If I used an Android-based smartphone or a tablet which support WLAN, would it be possible to access these network drives somehow? I'm entertaining the idea of getting a tablet, and it's important to know if I can access a larger storage than what would be available locally via an SD card (if such a slot even would be present on a particular specimen).
