Create Multi-Page PDF from separate PDF files

PDFCAT bigfile infile [infile ...]

PDFCAT concatenates a number of PDF files to create a single PDF file. Wildcards can be used in input file name(s) (but not in a folder name).

The output extension must be '.PDF' and an existing file of the same name will be changed to '.~PDF'.  Failure to read one of the input files (for example if it is password-protected) will cause the concatenation to fail and no output will be created.

If there is only one input file, a simple copy is done instead of 'concatenating' the file.

The errorlevel returned is 0 on no errors, non-zero on error.

Example:

PDFCAT newfile.pdf thisfile.pdf thosefiles*.pdf
