Hello everyone..

I have a wordpress website, it has like 50 users, they are a customer. In my end I need to upload pdf files, has a customer documents. Each customer has to login and using their account page to access his file. Mike access his files. John access his fils and so on..

I need easy simple plugin for that, I can’t find any or I don’t know what I have to search

Thanks in advance
