Dialog box to read a cloud file in Mathematica Online

Good afternoon.

I am an engineer that used Mathematica many many years ago during my Ph.D. Now I decided to try again and I ordered an annual subscription for Mathematica online.

I wrote a little script that reads a file:

data=Transpose@Partition[BinaryReadList["0077_1_20070101.BIN","UnsignedInteger16"],8];

This is the first line.
I would like to choose the correct file (in this case 0077_1_20070101.BIN) through a dialog window. Is it possible to choose a file from the Cloud Files directory?

Thank you in advance and best regards.

Bruno

For a local file, this works to bring up a file chooser:

SystemDialogInput["FileOpen"]

You’ll end up with the file path to the file you chose, which could be fed into your BinaryReadList expression.

For cloud objects, I don’t know if there is an analogous thing (I didn’t find one after a brief search). But you can get cloud objects with the various Cloud* functions. I supposed you could create your own chooser by first getting a listing of all the files in a particular cloud directory and using that list in a ListPicker (or some other sensible control).

Thank you very much, Eric. I appreciate your support.
