Files with the .moneydancearchive file extension are the daily backups that Moneydance automatically creates. The location and number of daily backups is set in Preferences.
(Moneydance menu bar > File > Preferences > Backups tab) https://infinitekind.tenderapp.com/kb/customizing-and-preferences/b...
They can be easily accessed via the Moneydance menu bar > Help > Show Backup Folder menu item.
They differ from your data files which use the .moneydance file extension.
Your data set is a folder not a file. It contains other folders and files. Its naming convention is yourdatasetname.moneydance. Data set folders can be found under HELP – SHOW DOCUMENT FOLDER.
There are two methods for making a backup.
In both cases you can select the backup location and as such it is good practice to set the location on a cloud server such as Dropbox, in case your hard drive fails.
Manual backup. A manual backup can be made under FILE (MONEYDANCE on Mac) – BACKUP EXPORT. The file naming convention is yourdatasetname-yyyymmdd-tttt.moneydancearchive
Automatic backup is set under FILE – PREFERENCES – BACKUPS. Auto backup makes a backup every time you close Moneydance. Moneydance only keep the last auto backup of the day, overwriting any previous auto backups for that day. You can set the number of backups to be kept. When this number is exceeded the oldest backup is deleted. The file naming convention is yourdatasetname.yyyy-mm-dd.moneydancearchive
A moneydancearchive file is a compressed data set.
The contents of a backup file is AES256 encrypted and provided you have set a password under FILE – PASSWORDS can only be opened by Moneydance by entering your password after using FILE – RESTORE FROM BACKUP.
When you FILE – RESTORE FROM BACKUP you do not overwrite your existing data set. This is in case you later find you need access to your old data set. A new data set is created with the naming convention – from manual backup yourdatasetname-yyyymmdd-tttt.moneydance the date time code taken from the backup file - from auto backup yourdatasetname (plus at number) e.g. yourdatasetname 2.moneydance The default data set location can be found under HELP – SHOW DOCUMENT FOLDER. You can delete old data sets you no longer want. You can rename a restored data set with Moneydance closed as you would any other folder provided you retain “.moneydance” extension. When you open Moneydance it will open in the “Welcome to Moneydance” window with the data set name listed on the right.
