Fielname pattern with space

Hello,

My file name are as follow

12-02-2013 12.48.24.m4v

With a space between the date and the hours/min/sec

I cannot find a way to make it work and I know it is because of the space in the filename...

Can anyone correct this to make it work ?

<Day>-<Month>-<Year> <Hour>.<Min>.<Sec>


thank you
