Upload document into a folder, default folder path

I have 2 web parts on AllItems.aspx (default view of document library) and both are showing documents from same library. Web part 1 shows all documents from folder 1 and web part 2 shows all documents from folder 2. When user drag and drop any document on the respective web part I want to upload the document in associated folder. for example if user drops document on web part 1, document should be uploaded to folder 1 and if user drops documents on web part 2, document should be uploaded to folder 2, possible? Looking for office365 solution.
