Sometimes you may want to open multiple files in the same window rather than in a new window for better file management.
When you use PDF Reader Pro, you can open multiple files in the same window and easily switch files for reading and editing, which helps you to be more efficient.
Here are the steps on how to open multiple files in the same window:
1. Click PDF Reader Pro on the main menu -> Preferences… -> General;
2. Select a new tab in the same window in Open a document in;
3. Click File on the main menu -> New Tab to open multiple files in the same window, or click Home on the toolbar to open a new file;
4. After opening two or more files, you can directly click the plus sign in the tab bar to create a new tab.
