Ghostscript unrecoverable error undefinedfilename

Question

PROBLEM

Many sites are trying to explain it, but error message is pretty unclear. In my case I had a lot of pdf files to merge and for some reason one file was a big problem.

Ghostscript unrecoverable error undefinedfilename

Answer 1

SOLUTION

If you got this message then merge files with asterix

gs -sDEVICE=pdfwrite -dBATCH -dNOPAUSE -dQUIET -dSAFER -sOutputFile=out.pdf *.pdf

If out.pdf is OK It means "your file path or file does not exist". Now is the message "undefinedfilename" already clear.

Answer 2

I received the same error by neglecting the dash before dBATCH. So

gs dBATCH ...

instead of

gs -dBATCH ...
