Sorry, I lost track of this thread.
In WingFTP Server, under "Ratio/quota" tab and the "Enable Disk quota" section there is a "Current Quota".
My understanding was that this will reflect the data that is in the directory at that moment. When items are deleted, that number goes down, and when added that number goes up, but to not ever exceed the "Max Quota" number. Is that not how this field works?
