Rich Text editor to upload file contents

Want to know if there is any rich text editor that has a feature to browse and upload file and also a feature to either view/download file contents if the entity configured has data filled in.

Is there something you can't do with the default file manager? See docs file manager.

For something more fancy for uploading you could try the File dropper

For a preview within the application of your file (only supported filetypes) you could use the Document Viewer from the appstore (after upload)
