To add a file to a merge queue using a Windows explorer, click on the ‘Add file” button in the middle of a queue area. Once the first file is added, the queue will transform into a table. Add more files with Windows explorer by clicking on the “Add file” button that looks like a “+” icon in the upper right part of the queue area. To make the process easier and quicker, explorer only displays PDF files. Simply select the desired file and press the “Open” button. After that, the file will be added to the end of the queue.
It is possible to add files by dragging and dropping them into the working area of the program.
