plugin features

Dear support,
I would like to buy this plugin to manage files on my web site, in particular i need to share with my client files divided in differnt folders categories.
For Example:
2017
- folder A
file a
- folder B
file b
- subfolder B
file c
My need:
1) is to upload a file in a folder/category and give the download role only to a specific user (also more than one) or group.
2) upload different files in different folder/category to a specific user with only one uploade procedure for example.
uplode file a, file b, file c to user A but with only one action and not with three different upload action.
2017
- folder A
file a
- folder B
file b
- subfolder B
file c
3) notify the selected file owner/viewer by emails
4) Allow external user to upload to a specific "group of user"/user in a specific folder/category
5) create a subscription plan for download from a selected category for a paid time user for expample:
one – month to download all the file available in the folder A

Many thanks for the support
