function popen and spaces in the path or file name

[freak]

Hi,

Have a problem with spaces in the function popen
Next example works fine:
....
$drive="c:";
$path="";
$file=" \\myfile.exe">" ;
$call = $drive.$path.$f ile;

pclose(popen('s tart /b '.($call).'', 'r'));

.....
Using "Program Files" in the path name
$path=" \\Program"> Files"; (error: "c:\Program ... " not found)
or
$path=" \\Program Files">"; (error: "c:\Program%20F iles ... " not found)

thus this will not work!!!!!!!!

Please help
