I don't own Mathematica, but have a (free) Wolfram Cloud account. I'd like to download all of the files in a given Wolfram Cloud directory to my computer. I've used CloudExport to create downloadable gifs and the like, and I can download files individually by clicking the Download link in the cloud directory, but have not figured out how to download in bulk.

To archive and download, e.g. the directory "Files" I've tried things like 

archive=CreateArchive["Files"]
CloudExport[archive, "zip", "Zips/testarchive.zip"]
(* CloudExport doesn't support "zip" *)

and

archive=CreateArchive["Files"]
CloudObject[archive]
(* creates a URL, but one that results in a 404 browser error *)

and other variants, but they all fail to do the job at some point.

Does anybody have a solution for this?

Give this a shot:

Export["asd1.txt", 1];
Export["asd2.txt", 1];
arch=CreateArchive[Directory[], (DeleteFile[#];#)&@CreateFile[]];
CopyFile[arch, Append[CloudObject["test.zip"], Permissions->"Public"]]

Replace Directory[] with your actual directory of interest, of course, and "test.zip" with your target directory.

  • $\begingroup$ Yasss! CopyFile to a CloudObject works, but I think it could be simplified to just something like CopyFile[CreateArchive["Files"],CloudObject["test.zip"]], where "Files" is the name of the directory to be archived. $\endgroup$

  • $\begingroup$ @brainjam if that works let me know. You'll definitely want the Permissions-><some permission set that is easy for you to access> though. $\endgroup$

  • $\begingroup$ The only thing I want to do is download the archive, which I can do from within Wolfram Cloud just by clicking on the newly created CloudObject or using the Download option in the directory view. So no permissions required. $\endgroup$

  • $\begingroup$ You can also just click on the URL that comes in the output though and it downloads automatically $\endgroup$

  • $\begingroup$ Turns out that the value of my $Permissions is Public, which maybe explains why I get away without setting Permissions. $\endgroup$
