Importing and Exporting Collections
Collections stored with previous Cumulus versions on the computer running the Client application can be imported (File > Import > Collections.) To store collections at any location other than the Cumulus Server, you can use the export function (File > Export > Collections.)
For sending a collection via email to another Cumulus user, a special export function is provided (File > Export > Mail Collection To.) However, don’t forget: Since a collection is always connected to at least one catalog, the recipient must have access to the respective catalog(s) to make use of the mailed collection.
To make use of a collection you received, you use the import function.
IMPORTANT! If the Remember Password option is activated in your Connect to Server dialog, any collection you export or mail contains your login information. Opening such an exported or mailed collection will connect to the Cumulus Server with your login and password. This means that the user who opens the collection works as you and has your permissions.
If the Remember Password option is not activated, the Connect to Server dialog will appear when an exported or mailed collection is opened.
