Read video files from USB - possible?


I am wondering if this use case is possible?

I have a USB connected to an android device and want to list a collection of video files from a user chosen directory on the USB.

So I want the user to be able to select a directory from the USB and I then want a file list of these files.

I have been researching and see conflicting responses as to whether this is possible or what plugins will actually give me this information.

Can anyone with experience give me a pointer on what plugin might help in going about this or if it is even possible?

Android is the only use case.
