## Add the possibility to run the script using Windows Explorer contextual menu when right clicking a file
# 1. Head to HKEY_CLASSES_ROOT\*\shell in the registry
# 2. Create a new Key named what you want (like say "FixSubtitles")
# 3. Set the "Default" REG_SZ value of that new key to the text you want to appear on the context menu
#      (like say "Fix subtitles in this folder")
# 4. Create another new Key inside the key you just made, and name it "command"
# 5. Set the value of the "Default" REG_SZ in that new 'command' key to run the command you want
# 6. cmd /C powershell.exe -executionpolicy unrestricted -File "C:\Users\vigi\Documents\fix_subtitles_in_folder.ps1" "%1"
# 7. -File Runs the specified script in the local scope ("dot-sourced"), so that the functions and
#      variables that the script creates are available in the current session. File must be the last
#      parameter in the command, because all characters typed after the File parameter name are
#      interpreted as the script file path followed by the script parameters.
