Nitro has a way to set the default view similar to Adobe. You can perform the following steps to change the settings which should make the attachments open full screen:
Click on the “File” option.
2. Click on the “Preferences” option.
3. Select the “Page View” option in the left panel.
- Select the “Fit Width” option from the default zoom drop-down.
- Fit width makes it look most like Adobe. You can choose whatever best suits your personal preference.
