I think this is a feature request, as far as I can tell SFFS doesn't currently do this.
Can we have "delay deletion by x days" and "move deleted files to folder.." working together so that when the file is deleted on the source it is moved to the folder, then after x days deleted from the folder? Like a recycle bin that auto deletes after x days.
I realise both of these options are currently available but they appear to work the other way round, the file stays in the original destination for x days then it's moved.
