Being cautious, I mv'ed the directory to .conboy.bak and created a new .conboy directory with the same permissions. The result was not as hoped. I have 91 note files. The new sync downloaded only 8 notes -- and some (most?) of those were broken. A pretty startling and distressing outcome.

In the new .conboy directory there also appeared a file called synced_notes.txt which listed the synced files.

Perhaps I should mention also that when I visited Conboy's settings after emptying the .conboy directory, the syncronization URL was already there and the Authenticate button did nothing. (Looked like maybe it was grayed out.) After discovering this, I presumed that the authentication info was somewhere other than the .conboy directory (where?) and I did _not_ need to reauthenticate. So I went ahead and tried syncing. And got 8 files (as mentioned above).

You said this was "_A_ way to solve this..." I thought I'd try to find a more focused approach, so I tried a diff on the Conboy/Tomboy filename lists from the N900 and my laptop.

I found one file on each machine that was not on the other (in both cases it was a general Tomboy info file). This situation may have been generated by a recent experiment with syncing a _third_ machine. I deleted both files. (After exiting the app on each machine.)

I've done a couple syncs at both ends since the deletes. Things seem to be okay. I'll report back if there are further problems.

Hope this helps someone else.
