launch pdf viewer and open file from a barcode

Does anyone know of a way to use a barcode (what type?  code 39, QR code) that will open a pdf viewer and a file?  If it will work, we'd like to put multiple files to open in one bar code, so all files would open at once with one bar code scan.

for example i am need one bar code to open all 3 of these files:
"C:\Program Files\Tracker Software\PDF Viewer\PDFXCview.exe" c:\a\test1.pdf
"C:\Program Files\Tracker Software\PDF Viewer\PDFXCview.exe" c:\a\test2.pdf
"C:\Program Files\Tracker Software\PDF Viewer\PDFXCview.exe" c:\a\test3.pdf
