The spawn command wants a single string so you should concatenate the parts of the command you want to execute. Also, if myfile is a variable containing the file name, it should not be in quotes.

Doing something like this in the loop makes it easier to see that you get the command string right:

cmd= 'cp ' + myfile + ' ' + file_dirs[i]
print, cmd
spawn,cmd
