Download usage refers to data (files are made up of potentially many millions to billions of bytes of data) sent over the internet in an attempt to preview (1) or download your files from our servers. Keep in mind that your files can be downloaded multiple times by the same recipient (for example if they share their link with another person). The 'Activity' tab located to the top right of your files provides details on how many times each recipient clicked the download link, etc.
The download numbers come directly from our hosting partner Amazon AWS (an Amazon company) and are the same numbers that appear on our bill from them. Under ideal circumstances, downloading from a good quality internet connection and staying within the same continent as the file server, it would take a little over 100% of the file size to download a file (due to the costs of HTTPS encryption and other standard protocol overheads).
Under ideal circumstances;
- if you uploaded a 10GB file and sent it to 10 recipients who each downloaded the file once you would be charged for 100GB of downloads
- if you were to cancel a 1 gigabyte download 10% of the way through we would charge you for the ~10% of bytes sent (roughly 100 megabytes)
Additionally each link to download a file can be used multiple times. For example Firefox, Chrome and IE allow users to pause and resume downloads often resulting in an overlap of downloaded data. Web browsers and especially 'download managers' (for example 'DownThemAll' and 'FlashGet' or 'cURL') can also use a link to start multiple download for the same file, this can dramatically improve download performance but often results in additional downloads.
- Under normal conditions most web browsers will only download the preview once for that session, so playing a preview multiple times shouldn't use more downloads.
