Exporting to a Smart Phone & Then Locating the File

Windows 7, Audacity 2.0.6
How do I export to a smartphone (not an I phone) and then locate the file on the smartphone ? Can the file only be exported once ?

Audacity exports files to the location that you select in the export dialog (provided that the location is writeable and the file name is valid).
Audacity has no special provision for writing to smart phones. You will need to refer to the smart phone documentation, or ask the smart phone manufacturer about that.

No, as many times and as many different formats as you like

If there’s any chance at all you may damage the sound file, make a copy of it on a USB thumb drive and keep it on a shelf or in your pocket.
