The Work Directory is a folder used to store all the customizations of this instance of Yioop. This field should be a complete file system path to a folder that exists. It should use forward slashes. For example:

 /some_folder/some_subfolder/yioop_data

(more appropriate for Mac or Linux) or

 c:/some_folder/some_subfolder/yioop_data

(more appropriate on a Windows system).

If you decide to upgrade Yioop at some later date you only have to replace the code folder of Yioop and set the Work Directory path to the value of your pre-upgrade version.
