Using javascript to extract pages from PDF

[Sean 1982]

Each month I get a large pdf file that I need to extract pages from and resave. The page numbers rarely change so this can had been working:

this.extractPages(0,1, "table1.pdf");

this.extractPages(2,15, "table2.pdf");

etc. for many more tables.

I recently "upgraded" to Adobe Acrobat Pro DC version 2021.005.20058

the code no longer works. I get an error message:

RaiseError: The file may be read-only, or another user may have it open. Please save the document with a different name or in a different folder. Doc.extractPages:1:Console undefined:Exec

There is no possible way for another user to have the file open - I just created it. I have searched on this error and seen many solutions, however none of them solve the problem.

Go to Edit (or the Acrobat app menu if you're on a Mac) - Preferences - Security (Enhanced) and disable Protected View Mode (or something similar).

[Sean 1982]

That's not it. Using a PC, Protected View is already off.

How many pages are there in the file? What's the name of the original file? Where is the original file located (under what folder)?

[Sean 1982]

Original file has 1084 pages, named "alltables.pdf".

all in folder c:\macros\adobe

Is there already a file with the name you're trying to save it under in that folder?

[Sean 1982]

No, i don't have any other pdfs in that folder.

Are you able to manually extract those pages from the file?

From where are you running the code?

[Sean 1982]

I can extract manually. I am running the code by opening "alltables.pdf", then go to tools > javascript and open the debugger. I paste the code from post #1 into the console, highlight the code, and execute by ctrl+enter. When I do this, I get the error message.

Protected View is NOT the option that matters. You need to turn off Protected MODE. The job of this option is to stop files from being written without a prompt, and so if you want to do that, the option will stop you...

[Sean 1982]

Ah, I see. That option is checked, but also unable to be changed (grayed out). I think I'll have to check with my workplace's IT staff to try and chnage it. Thanks for your help.
