To help you all with batch add/remove/modify these files to save time,
I've put together some quick windows cmd scripts.


##These .cmd files assume you have MKVtoolnix downloaded and in default path:
##C:\Program Files\MKVtoolnix\mkvmerge.exe

##Feel free to edit to your respective paths.

##You will need roughly double the HDD space to execute these cmd arguments
##After running, you can delete the original files if to your liking.

##For English Audio only, but maintaining all subs:
Simply drag the first video file onto "engaud.cmd"

-this will create a new file with "new_" as a prefix in same folder.

##For English Audio only, and only English subs:
Simply drag the first video file onto "engaudsub.cmd"

-this will create a new file with "new_" as a prefix in same folder.
**If you want certain subs, simply right-click to edit "engaudsub.cmd" and where it has
  "-s eng" simply add whichever subtitle you want. ex:"-s eng,fre,spa" will render
  only English, French, and Spanish subs in output.

##For adding Atmos Audio to files:
First move all audio tracks for season to same folder as videos; then
Simply drag the first video file onto "atmos.cmd"

-this will create a new file with "new_" as a prefix in same folder.

***If wanting the new file to rewrite to a new folder or location, simply edit cmd from:
"-o ".\new_%%A"" to "-o ".\NEW FOLDER NAME OF CHOICE\%%A""

##I've done my part; the rest is for you to figure out.
