Does anyone know to change PDF metadata, in particular to synch Created & Modified dates with those of the actual file ?
The PDF files in question have *no* Modified and/or Created dates in the metadata - so maybe syncing is the wrong word - I just need the info copied where this info *not* in the metadata - if all info has to be synched that's probably okay too.
I'd like to be able to batch process files so a GUI isn't necessary. OTOH, I suspect that PDFTK
could possibly do this or ExifTool
probably, but they both command line with minimal (for my level) help or instructions and I cant figure them out.
e.g. ExifTool says:
-[GROUP:]TAG<=FILE Sets tag value from contents of specified file
The download has to be renamed to exiftool.exe for command line use - on download it's exiftool(-k).exe
That's as far as I got there...  a link
to info about PDF tags linked to from ExifTools [/edit]
NitroPDF pro says:
Tip: Not all the document information can be modified. Many fields are set at the time of creation or when last edited. For example, creation time, creator, producer, optimization, PDF version, etc.
so that doesnt seem to be of help.
It appears that Benubird Free version does "PDF metadata to file metadata syncing"
. Benubird discussed here
But that's probably a bit like using a sledgehammer to hammer in a tack ?
There's software out there that claims to do this - expensive and I dont know would I trust a lot of it (it's obviously a big market and there some very basic tools being sold at very high prices out there - e.g. I came across what was being sold as a PDF printer for Word, for $70, $30 to split a file etc etc. [all at same site] ouch. ouch.)
Edit/ added another link above for exiftools info
