I think you've labeled your bat file and properties file the wrong way around in your original post.
Anyway, if you have your username, password and URL in the properties file, then you don't need to include them in the command. Just reference the properties file with the -c option
E.g following should work directly from the command line
imbulkloadclient.bat -c ..\conf\imbulkloadclient.properties -f CSV -i \Users\XUZ\Documents\user.csv -v
-v is for verbose logging. Should be output to the screen and the log file.
Note: You may need to start the command prompt as administrator to ensure that you have write access to log file.
