easy way to select / view video files?

[InGearX]

I got my mom galaxy s3 she is getting used to it... quiet ok ...

I want her to get used to being able to see some entertainment videos when YouTube is not available ...

so what's a very good easy way for her to see video that are available?

best if she can see folder the structure I made on a 64Gb MicroSD - about 30GB of videos she would enjoy ...

so far I'm thinking either generic video player to select - but organization is poor ...

or the ES File Explorer ...

again seeing the directory structure (per genre) I made is much preferred ..

+
|-MOVIES
|-SHOWS
|-MUSIC-VIDEOS
|-MOVIES-DOC
|-Educational
|-How-to
|-etc...

any advice and help are very much appreciated ...

thank you...
