IOError: [Errno 2] No such file or directory:"filename.exe -type png

Use 'os.system' not 'execfile'. 'execfile' is for executing other
python scripts, not arbitrary command line.

Try this:

import os
....
....
os.system("filename.exe -type png -source sourcearg -file
filename.png")

try
execfile("d:\pathto\filename.exe -type png -source sourcearg -file
filename.png")

error output
IOError: [Errno 2] No such file or directory:"d:\pathto\filename.exe
filename.exe -type png -source sourcearg -file filename.png"

be careful with your '\'s they tend to get interpreted as escape
characters. You can prefix the string with an 'r', double them up or
use forward slashes.

One of the following should work:
r"d:\pathto\filename.exe -type png -source sourcearg -file
filename.png"
"d:\\pathto\\filename.exe -type png -source sourcearg -file
filename.png"
"d:/pathto/filename.exe -type png -source sourcearg -file filename.png"

That does not do what you think it does, see

http://docs.python.org/lib/built-in-funcs.html#l2h-26

You need os.system() or, for more complex applications, the subprocess
module.
