The files should all derive from System.FileDocument, so you could do a retrieve on this entity to get all the files in your application. If you know your uploads are all of a certain specialisation entity, then you could just retrieve that instead. You can then show the results on a page in your application, and add download and delete options as required.
Good luck!
Hi Iqbal,
Just retrieve your entity on a page in listview which is generalised with System.FileDocument.
Add one delete button for deleting the object & add another button(download) -> call a microflow on this download-> inside this microflow just take download activity & download your file.
Hope you like the answer
