Data Package feature has .datapac or .dpack file extensions and can be opened by any zip utility. Data Package feature allows you to export large databases that contains images or any blob data correctly. It also allows you to protect the data package with a password. Data Package file format uses the ZIP file format to package data and it is also readable by and useful for third party applications.
Why should I use Data Package Export/Import?
Exporting data as an SQL script is not suitable for large data or blob types. The data can corrupt or importing large SQL files can fail. Data Package feature allows you to export and import your data in a secure way and by doing so you can share your data with third party applications.

27.2Importing Data Package
The data packages can be imported from the same or different databases. To import a data package, you should first browse the package and assign the source-target tables. They will be automatically assigned when you browse the package. If the data package encrypted with a password, you need to enter the password first then browse the package file.
Why should I assign the source/target tables?
Data Package import feature allows you to import data from different tables. This means that the target and source table names must not be the same but their table structures must be the same, otherwise data will not be imported.
