Would it be possible to have some sort of progress indicator for downloading files?

For example if we would like to import: Import["http://lieanalysis.com/exampledata/os.mx"]

It would take a while, it would be nice if you have some sort of progress indicator (like mathematica uses for ExampleData)

Use URLSaveAsynchronous to download, then Import the downloaded file. There's an example in the documentation about progress bars.

Be aware that I experienced some problems with this function. In version 11 sometimes it would get stuck after the download has finished. See the discussion:

  • $\begingroup$ Thanks for your answer, somehow I must have overlooked this function. Will accept you answer when I'm allowed :) $\endgroup$ Commented Dec 6, 2016 at 13:53
  • $\begingroup$ @FrankMartin Well, there's URLSave, URLFetch, URLFetchAsynchronous, URLSubmit, URLDonwload, URLRead, Import, HTTPRequest and so on and so on. Some are deprecated and won't show up in auto-completion. Not so easy to find the right one. Once again be careful because this kept hanging for me on Windows when wrapped in WaitAsynchronousTask. $\endgroup$ Commented Dec 6, 2016 at 13:56

    $\begingroup$ Maybe it is worth mentioning that "Content-Length" header has to be present for progress indicator to show progress correctly. It usually is there but happened to me that it wasn't. $\endgroup$ Commented Dec 6, 2016 at 13:56
