There are 2 ways to download content from CDAC - individual item downloads, or the briefcase download.
Individual items are easy if you are just wanting a handful or less of content.
The briefcase is helpful if you are looking to download numerous content at one visit. Add the items to your briefcase, then when ready, download the entire briefcase as one zip file.
Your membership has daily download limits, so keeping that in mind, here's how the downloads work:
Every time you hit the download button, it counts as a download. We have no way of knowing where you actually saved the content so the download count it based on clicking the download button. The count 'resets' every day at midnight US Eastern time.
If you have 6 items in your briefcase, and you click download, but don't actually save the file, and try to download again, it will now count 6 downloads plus another 6 downloads, for a total of 12. So please be sure you will save what you download when you click the button, as it is counted towards your limit.
The daily limits are reset each night so you can continue the next day to download additional items!
