drag & drop to another FileExplorer

Hi,

I have working one FileExplorer with database as content provider and drag&drop works fine within this control

but I need to be able to copy or drag& drop to second FileExplorer also. How to configure

UploadPath etc to make it work?  Assuming that second FileExplorer will have separate db table

for files list. Currently first FileExplorer has all Path set to "Root".

thanks
