When I saved my batch file to run the ymdt executive, I had problems because my folders had a space in them and%~dp0 didnt work
The quick start didnt prepare me for options,
but yo guys should place these places to figure out the right configuration for the batch

I used this instead
@echo off
php %~sp0\ymdt %*
~s causes the shortening of the locale, whiel d is the direct locale and if you have spaces gives you problems.
Just a suggestion.
