As administrator, I would like to upload files in your FILE MANAGER” in the backend, and store those files into users directories (so that once user log’s in, he/she can see the file I uploaded for them)
Can this be done?
you can upload files from Front-end even Admin. And for upload to specific user we have already addon for this called: File Manager User Specific Addon. Here is more details: najeebmedia.com/wpfm
