FlexiPDF can quickly join multiple PDF files into a single document. Drag and drop any number of PDF files onto the open (but empty!) program window of FlexiPDF.
Alternatively, proceed as follows:
| 1. | Choose the command Document | group Edit | Join  . |
| The dialog box Join Files appears. |
| 2. | Add more files or entire folders full of files by clicking on the Add Files or Add Folder buttons. |
| When you add folders, all PDFs in the folder and its subfolders are added. You can add an unlimited number of files. |
| 3. | The order in which the files are displayed in the list is the order in which they are joined. To change the order, click on a file and change its position in the list using the Up or Down button. |
| 4. | Click on Join to start the process of merging the documents together. You will then be prompted to specify a file name for the new merged document. |
| 5. | When the process is complete, FlexiPDF will ask you if you would now like to open the new document. |
