how does it work (consider this as the readme) :
-Number of file :
You have a file list with 1500 files and want to separate them into N folders (regarding only number):Select them all -> Alt+F5->choose 'mover' ->check Separate per file number->put a value in the edit box (between 1 & 10000)->press ok
The plugin creates N folders containing the desired number of files , the last one contains the "rest"
-Separate per date
Filelist->...->check separate per date
If you do not check other boxes it will uses only the year to create folder
otherwise the folder structure can be (example):
-Use day : 20050523 , 20050530, ...
-Use month : 200505, 200504
Folders will contains files with corresponding dates

That's all...
