Feature request: To show before downloading "file already exists: Open/Download Again"

My job requires me to refer to a lot of Acts/Rules/Notifications/Bye-laws etc. Therefore, I download a lot of documents.
Sometimes this leads to multiple instances of same document being downloaded. For example “xyz.pdf”, “xyz (1).pdf”, “xyz (2).pdf”.

Feature request: The dialog box that appears before downloading should show that “file already exists” and give an extra option to “Open” the existing file.

Why this feature is important:

  1. Everybody downloads documents, from students to working professionals.
  2. Declutter storage. The file management system on Android is not as intuitive as windows.
  3. No feature to preview document before downloading exists.

Please reply if you think it makes sense.
Thanks.
