You can append a single file to the end of another file with a copy of the Input file being placed at the end of the Output file.
1. Select the option “[50] (*.*) Append (Concatenate) files” from the list of available special processes, then select the file format of the input file from the File Format dropdown list. The output file must also be saved in this format.
2. From Select Input File(s)/Folders To Process browse for or type in the path to the file or folder you wish to process.
3. Place the output file information into Select Output File(s) by browsing for or typing in the name and location the file will be saved at. The format must match File Format in Step 1.
4. Click the Add button to add the task to the conversion task list. You may add multiple tasks to the conversion task list before initiating the conversion process by repeating Steps 1 - 4 as necessary.
5. Click the Convert button to start the process.
Alternatively, you can append multiple files to the end of a single file by using the folder option to select the input folder, then adding the file format to the end of the path (e.g. *.doc , *.htm, *.txt). A single file name of the same type must be specified as the output file. It may be located in the same folder or a different one, as desired. For example, input files of C:\BusinessLetters\*.doc and an output file of C:\BusinessLetters\ManyLetters.doc will append all .doc files found in the BusinessLetters folder to the ManyLetters.doc document.
