Problems with spaces in command line file names

[Rulonv]

When using the following command line syntax

wincmp3.exe [ first_file second_file [result_file] /i=UserName] [options]

CompareIt cannot determine the correct file name if either 'first_file' or 'second_file' has a space character in its filename.

Is there a fix for this?

Have you tried using quotes:
wincmp3.exe "long file name" "another one"
