Update: MSPC never finished backup, though tablet message implied that it did. Restarted everything. Tried again, MSPC backup completed. 

Now, armed with tablet and PC library backups, trying Batch Import again, again being sure Avoid Duplicate Songs is selected. Seems to be counting through songs more quickly. 

But unexpected: When Batch Import encounters a file of the same name, it stops and asks me to select an Action (Use Original File, Rename, Skip, etc). Since I told it to Avoid Duplicate Songs, why does it not just skip them? What does "Avoid" mean?

So, I select Skip File and check Apply selection to all conflicts. But is vague, I can only hope that "conflicts" means the current conflict, same File name. (Not sure what other conflicts would be possible...)

More oddly, it stopped on just one file about 3,000 files into the process. But many more duplicate files exist, a few thousand since I'm doing Batch Import on my PC's entire Tablet folder, hoping Avoid Duplicate Songs literally does that, so only truly new songs get imported. The first 3000 had many duplicates, probably 80% them, so why did I not get a same file name action request many times?
