Structures can be imported to Database Manager by loading them from an external MOL-file or SDF-file. In contrast to the pasting of a structure, when you load from an external file you can add structures to more than one record at a time. This allows you, for example, to assign a large number of structures to library spectra when importing an external library to Mass Frontier.

To import structures from a file:

1. Select the records you want to add structures to.
   
   
2. Load the structures by choosing File | Open | Structure.

When adding more than one structure to your records, the structures are added in the same order as they are present in the file, from the first to the last selected record. If the number of structures in an external file is greater than the number of selected records, structures are added only to the selected records. If the number of selected records is greater than the number of structures in the file, all the structures are added, and some records remain without structures.
