While on the computer, there will be times that you may need to upload documents to another website. For instance, in google docs, there may be a time when you want to put a document into your files or even share them with someone else on the google drive. To do this, you must either upload it the longer way by clicking opening and adding it.
However, you could also drag it and drop it into the folder. To do this, you must have the drag hand which is the hand that will hover over the document. Then you drag it to the correct place. In audio, you can drag an audio clip by using the drag hand from the Viewers audio tab to the Canvas edit overlay or to the timeline.
