Guided Action Sanitize Document

Hello everyone. I need to sanitize a big file, 26k pages. I found out that my pc cannot handle it, so I tried to divide into small files of 10 pages and using guided action to sanitize every document in the new folder.
The problem is this:
every time Adobe sanitizes a new document it gives me a choice to save the file somewhere.
Is there a way to fully automize this thing???

I cannot sanitize heavier documents otherwise for some reason Adobe crashes.

Help would be appreciated a lot.
