Hi, I had different experience, but before I list all of them I would like to mention:
I fould the folder, where could be the local database stored. (Fantastic for local backups!) Please help me to prove it: "C:\Users\NAME\AppData\Roaming\Evernote\conduit-storage\https%3A%2F%2Fwww.evernote.com"
(I have never seen any folder named this way "https%3A%2F%2Fwww.evernote.com") anyway:
The Evernote 10 does not modify the database files used by legacy version — which means, that it creates its own local database or cache.
When ethernet turned off, the notes I did not visited yet were unreachable. Only the headlines, no content. The content appeared after switching ethernet back on.
Once visited, the note appears instantly when opening again later.
The note I am opening for first time with Evernote 10 takes longer to load — it is obviously downloaded from the cloud. Which brings me to the next point:
How the syncing works? Do I have to click to every single note to get it localy? Even after a few hours of EVN 10 running it was the same. In old version everything was downloaded to the local database.
The folder with the database which I am mentioning above contains a SQL file which get bigger after each time when another note is opened and downloaded — as described in point 4.
