File Sharing Website using Django

#django #python #webdev

Do you know Django is Fabulous? I love this Framework.
In this post, I am sharing you a new Django Project 'Share-o-File'. In this project, user can create account and share the files (PDF, Images, Audio, Video etc.) after Login. Other users can View and Download these files but login required.


Functionality of 'Share-o-File':-

  1. Signup
  2. Login & Logout
  3. View & Download the files
  4. Upload and Delete Files
  5. Search Users and their Files

Source Code:-
