There is a common issue with zip file that contain empty folder when it is extracted the empty folder become a file instead of folder.
Because of the above issue many open source distribute their zip file where it has empty folder they put in some kind of place holder file to ensure the folder will be created when unzip.
Is that possible to do similar with Yii zip file distribution?
There are some "empty" file in empty folder but "demo" folder where blog and others that do not have "empty" file.
I use the PHP zip function call to unzip Yii distribution file and found out that several empty folder were create as file instead of folder because it is empty.
