For instance, when I opt to send from Audacity, I get a pop up with a listing of possible destinations … but I need to send mine to ACX and I don’t know how to make that happen. Some other files I need to send to Dropbox but, again, how do I do that?
What is the version of your audacity application? What is the name and version of your Operating System?
For instance, I am on Windows 10, Version 1903 (OS Build 18362.657), and using Audacity 32 bits, 2.3.3.
but I need to send mine to ACX and I don’t know how to make that happen.
You really should export to WAV first, then [u]master your audiobook[/u] including running ACX Check to make sure you are in compliance with the standards. Then make an MP3 (and maybe save a copy for yourself) before submitting to ACX
Some other files I need to send to Dropbox but, again, how do I do that?
I’m not a Dropbox expert but I believe you need to make a file first before dropping into your Dropbox.
