Odd. I tried again and now it is working.
This time I re-formatted the USB stick to FAT32 (it may have been NTFS, if that matters). The "Send To" had the USB stick listed and I'm copying files now. Nice!
I didn't know one could do a "Copy Paste" from the Playlist view. I'll try that with my next Playlist file copy.
UPDATE: The "Send To" did not work. It did not copy just the Playlist songs - it copied all my music (even songs not on the Playlist) to the USB stick.
Also, the "Copy Paste" does not work from the Playlist view.
This is a real PAIN.
Using "Send To" would be desirable because then I can convert any FLAC files (which don't work on my car player) to MP3, but that seems to start a "Snyc" process that wants to analyze my entire audio collection.
However sometimes it gives a "transfer" button instead of "sync". MC has my USB stick identified as a "handheld" device. Transfer makes sense, I don't want to sync anything. But I don't know what determines which MC choices to do.
But the main problem with the Send To method is that it wont let me select a folder on the USB stick to copy to. Trying a second time to use Send To, now displays all my selected files a duplicates and won't let me do anything. Also it wants to add a folder for Artist/Album and I just want all the songs in the same folder.
So I'm going to try the Copy tool.
Using the Library Tools>Copy function allows me to select the folder on the USB stick to copy to, but it won't "convert" the files to mp3, and for some reason it is adding a number (track number?) to the beginning of each file name. I had to manually deleted that number (looks like "01-02-filename") from each file.
I spent over an hour copying, converting, renaming 50 audio files. There has to be an easier way. And please don't say "read the Wiki", there is nothing in the Wiki that describes this process.
