The Chrome browser will typically download your files rather than open them. You see this happening in the StaffCV app when you click on a CV, Cover Letter or other attachment.
However, you can 'tell' Chrome to open the file instead of download it.
- When you click to download a particular file type (e.g. .txt, .doc, .docx, .pdf), look at the bottom of your browser window, where you see the little down arrow next to the file name.
- Click on this down arrow, and you will see an option 'Always Open Files of This Type'.
- Click on that option, and that file type will always auto-open in future.
(Note, you'll need to do this once only for each file type you come across).
