mass shrink of .pdf files

Have ~19,000 .pdf files accumulated over two years of a project.  Now, need to archive but retain quality.

Total size for data store is ~20GB's,  Would be great to get to less than 2GB's.  Typically files will shrink 10x when using Acrobat Pro, but need to do all 19,000 files "at once", or at least automagically.

Solving the 19,000 files is the question, but better yet if there is a systematic way to routinely shrink files for the next project as they're created?  Bonus if so...

What version of Acrobat Pro do you have? In Acrobat X, you need to go to File->Action Wizard->Create New Action.
In the "Start with" box, choose "Ask when action is started", then go to "Document processing" and choose "Reduce file size".
Give your action a new name (like "mass reduce pdfs") and run it whenever you need.

Create new action
As for doing this for a new project, just do the same steps but choose "A folder on my computer" on "Start with" and "The same folder selected at start" on "Save to", then run the action daily/weekly/etc.

HTH,
Dan

OK, looks exactly like what am hoping for.  Just not experienced (didn't even know) about automation in Pro.

Set the job up on a test location (an NFS.)  Setting make sense for the most part, but am getting prompted for "save as" type settings (i.e. what version and "do you want to save changes...") prompts.  I found the tick box, to eliminate version setting prompt, but how to tell Pro to simply save the file for each to avoid having a prompt at each of 19k documents?

Thank you for help, this is a valuable exercise.  BTW on Adobe Pro XI

Weird. Just tested and it only asked me about the input folder and the output one. No other prompts.

Do you, by any chance, have "Prompt user" checked on the first step?

PS: As for not having the "do you want to save changes" prompt, simply use "The same folder selected at start" on the last step ("Save to") and check "Overwrite existing files"
