# Opening PRIMER files

**File>Open**>(File name: <ins>Ekofisk macrofauna counts.pri</ins>)>Open will read in the existing Ekofisk species-by-samples array. The default file types are any of the PRIMER 7 formats, though earlier formats (Windows PRIMER v6 & v5, DOS v4), text and Excel files (commonly used for initial data input) are available. These are listed in detail on the first page of this section (Section [1](https://learninghub.primer-e.com/books/primer-v7-user-manual-tutorial/chapter/1-opening-editing-and-saving-data-file-edit)).
