Send a command to another program

[slideray]

I'm trying to make a script that will send a command to the file manager to open the location of the file that is currently being played.

function gotofile()
  filename = string.format("%s", mp.get_property_osd("filename"))
  filepath = string.format("%s/%s", mp.get_property_osd("working-directory"), mp.get_property_osd("path"))
  os.execute('C:\\Tools\\doublecmd.exe -c -t "' .. filepath .. '\' .. filename .. '" &')
end

-- Key-Bindings
mp.add_key_binding("1", "gotofile", gotofile)

Logically, everything seems to be correct, but the script does not work :(
Can you tell me how to do it right?

It turned out to solve the issue. It was enough to specify filename, like this:
os.execute('C:\\Tools\\doublecmd.exe -c -t "' .. filename .. '" &')
