I wanted to sync my kepass file to skydrive.
So I put a copy on SkyDrive and then selected "synchronize with File.
Result: both password files are empty!
By 'empty' do you mean that a database Name is shown on the KeePass Window Title (i.e a database is open) and the KeePass View is white (not gray), but otherwise it shows no groups in the left panel, or entries in the right panel?
If no column heading are shown, check in the 'Configure Columns' dialog accessed via View>Configure Columns... and check one or more columns to display them.
Please describe what you saw at the time you synchronized.
Are you sure that you synchronized the correct database?
Do you have a backup copy of your database?
Fortunately I had a backup, so the immediate emergency is over. :-)
The database was open, there was one empty folder (Passwords) and nothing else. Possibly the two demo passwords.
The file size shrunk von 70KB to 21KB on both files.
I am using windows 8.1.
By now I have gotten the sync working (manually) by importing the passwords from the backup to the emptied local file and then sync'ing.
This afternoon I will try to reproduce the problem with a screen recorder running.
Lots of Greetings!
Make sure you have the "recycle bin" turned on, File > Database Settings > Recycle Bin.
Did you do any large scale editing (e.g. moving entries by copy & paste, or deleting duplicate entries etc.) in one or both of the databases immediately before (or sometime in the past) before you synced the two databases?
