Modifying PDF file in place

Biganon
Hi,

So I have many big PDF files attached to my entries. I find them in ~/Zotero/storage. My question is : can I modify them in place ? I was thinking of compressing some of them, using ghostscript or whatever. Will Zotero realize they've been modified (based on their hash e.g.) and sync accordingly ? Or do I risk losing data ? If so, how would you batch-compress your PDF files ?

Thanks in advance.

    There's no risk of losing data. Zotero should typically realize that the file has changed and resync it (based on the file system's modified time).

    No good idea on compressing PDF files -- really depends on what you're after, too. If you have acrobat pro, the automation tools are quite good and easy to set up.

    Thank you for your answer. To compress, I usually use the following command :

    gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf
