double-click to start file in native application

meanwhile I enyoi Vole Windows Expedition a lot.
Explorer Factory with its preview is a great help, and if I find "late minute errors" there,
it is a pleasure to start the native application / the open-with-program by a double-click
instead of a single click..

I use this double-click feature also as a workaround, to start my
mp3- and mp4-files with the VCL-Media-Player (opens on second screen in full-screen-mode
automatically). But until now I have to stop the preview-player first. It would be great, if this could be done via my double-click.

In Project-Presenter-Mode such a double-click-feature would be also very helpfull > in my case for instance to show excel-files in Excel with resepct to their build-in interacitity.

For pdf-files I prefer the Xchange-Viewer (Pro), which still allows to start Batch-files via links. I use this to add voice-comments to sections in my pdf-files (in wav-format / started wtih a first click and stopped at any time with the next). But I had to realize, that starting the PDF-Xchange-Viewer in Factory-Mode and clicking on my links had no result (as if such attempts would be stopped by process-killing).

Please let my know
