Than you for contacting us.
When you enable syncing in Moneydance, it creates a unique folder for the currently open data set in a special (hidden) folder.
Moneydance reads and writes to that folder in such a way that there will never be any conflicts. Filenames are unique and the data is encrypted using your sync key. All changes are recorded in this folder and if any of the changes cause conflicts then they are resolved by checking timestamps that are internal to the file (ie not the file modification date). Those are the files that you see in that folder, they are called .mdtxn files and they are created when there are any changes to your data set. These files should be periodically integrated into the main data file.
The latest update limits the amount of these files.
You can upgrade to the latest version 2017.4 of Moneydance from here:
