How to get a submissions report on iPad

Hi, 
On a form I integrated Dropbox. The individual submissions go in the Dropbox folder, however, the submissions reports, pdf or Excel do not go there. On the iPad it says, Download complete, but I cannot find the report. I also checked with a PC, and I have the same result. However, with the PC I find the report in the Download folder, which is not the case with an iPad since there is no Download folder. I need to know how to get a report with an iPad. 
Thank you
Bob

I do not have iPad to test this. 

I searched on the web and I found following articles that may help you to find downloaded files:

Thanks.  However,. this does not help me.  I had already spent hours on the web to try to find a solution.  The question is "How can I select where the submissions report are saved?" If there is a way.... 

I asked one on my colleagues that had an iPad and he told me that for PDF files, you have to to use PDF reader (Adobe Acrobat) and the files should be shown there.

When you open the PDF file you have to click sharing button and then Copy to Adobe Acrobat

Then the file will show like this.

For the Excel, you have to use Import with Numbers app, wish is a default application on any iOS device and save the data there.
