Mycloud app on ipad4: how to close a file once open

I am using the mycloud app on ipad4: how do I close a file once open? And can I search for a file?

Hi, once you open a file like a picture for example, you can press the upper left part of the screen to go back to the explorer window. Currently the option to search for a file is not available.

I followed your suggestion but file stays open. Is there anyway to close the file? I don’t say a password file to remain on the screen.
