I just upgraded my edition of Evernote to Premium, which seems like a pretty good idea.
I use Evernote a lot as a note capturing tool, because I can easily format the notes to work as a mini-outliner, as well as capture pictures, pdfs, screen-shots, etc. I have plenty of other alternatives on my iPad and Mac, but I do like the convenience of Evernote and the fact it synchs all of my various devices effortlessly.
So I was surprised when I upgraded and discovered that something had caused all of my notes to duplicate themselves during the upgrade. I ended up with a lot of duplicates. I searched around for someone else who had run into a similar problem but I didn't find anything.
I ended up manually sorting through and deleting all the duplicates. But the job was tedious and annoying because you can't highlight multiple notes for deletion. You have to highlight the note, choose delete, then confirm, for each note. It took awhile.
There might be an easier way, (there probably is) but I didn't have time to look for it and it wasn't obvious anywhere in the documentation. But it also shouldn't have been necessary - unless I did something wrong to cause the duplication.
Oh well. It's done now. But I thought I'd write this up in case someone else has the same problem and finds this blog post in their search. Please add a fix in the comments, if you happen to come across one.
