We are interested in your product, however I have a question. Is it possible to split a PDF by the bookmarks and name the new files using the bookmarks?
=============================
You can use "bookmark" or "bookmark2" option to name the output PDF files,
bookmark : split PDF file by bookmarks, append page number to filenames
bookmark2 : split PDF file by bookmarks, without page number in filenames
for example,
"C:\Program Files\VeryPDF PDF Split-Merge v3.0\pdfpg.exe" bookmark C:\A.pdf C:\split
"C:\Program Files\VeryPDF PDF Split-Merge v3.0\pdfpg.exe" bookmark2 C:\A.pdf C:\
"C:\Program Files\VeryPDF PDF Split-Merge v3.0\pdfpg.exe" bookmark2 C:\A.pdf C:\out\
