> How the create recycle bin in folder.
You can't create recycle bin in each share folder.
Thus when you delete some file in share folder from *remote PC* (e.g. using NasNavigator2 to open share folder and operating), *the file is absolute lost* (and it doesn't go to trash box in Desktop).
So it is recommended to set VSS (Volume Shadow Copy Service) on ahead, which is Windows function.

* If you delete some files in share folder from Remote desktop, or local access, the file will go to trash box in Desktop.
In this case, you don't need to use VSS to recover files.
