The files I'm attempting to download are so large that my download never finishes. What can I do?

Some older Web browsers set a limit on the maximum file size that can be downloaded. For example, Internet Explorer 6 will not download files larger than 2GB, and Internet Explorer 7 will not download files larger than 4GB.

If you're having trouble downloading a large study, we recommend you try the following:

  1. Verify that you have enough hard disk space for the download.

  2. Update/upgrade your Web browser.

  3. Try using a different Web browser.

  4. Download a single dataset at a time.
