Simplify and short the language

[EV21]

I think shorter expressions (like in the 3-dot-menu) are the best solution.

Is it necessary to have all the "this" in the expressions. I think with "this" it is not more clear for the user where he clicked at.

some suggestions
Open folder instead of "Open this folder" - maybe just Open could be enough
Share folder - maybe just Share
Open file or Open
Share file or Share
Show picture or Show
Show PDF or Show
Show video or Show
Play - (audio player)
Stop playback - (audio player)
Open in Gallery (without the "app" suffix)
