Combine files stuck on checking for security settings?

[iceny]

Adobe Acrobat X Pro 10.1.1 on Mac OS X 10.6.8

I've been trying to combine 2 pdf files (scanned to pdf using Preview on Mac) in Adobe Acrobat. However, it keeps getting stuck on checking for security settings for a long time (see screenshot below).

I checked the security settings on each pdf file and they both are showing no security.

I opened the original file using Preview, open the Print window and saved it to PDF under different name and still I can't combine the files. Is there any other way to get this done? I've been searching on Google and this forum for hours and found no solution to my problem.

Thanks.

You might want to open them in Acrobat and use preflight to check the consistency of the PDFs. Then possibly save them to new PDF names in Acrobat. See if the new files can be combined. It sounds like a structure issue, and maybe the save as will resolve the structure problem. Have you tried opening one and then use the Insert Pages option to insert the other document?

[iceny]

Bill, I'm not sure which option to choose for the preflight. Can you please explain more?

I did try the Insert Pages option and it works. However, I would still love to know if preflight will fix the security settings issue when combining files. Surely, Insert Pages won't be as efficient when it comes to combining more than 20 pages

Thanks!

Insert Pages is the normal tool for combining PDF files, possibly many thousands of pages; the special thing in the File menu is a new tool, and not any more efficient in its resuls. For combining just two files, it hardly seems even quicker to use.

After combining files it's important to use SAVE AS PDF not just SAVE. This does some housekeeping, otherwise the resulting file is much larger than it needs to be.

Thanks Test Screen Name for your reply. As it happens I have many PDFs I wish to combine in a particular order. The Combine Files Tool was designed for this situation, with many, many files. But sadly this tool does not work.

bencncn: clearly Combine Files should work for you and it's a bummer that it isn't; however, Test Screen Name is still correct that using Insert Pages is a workaround to the issue that you are experiencing: on Mac at least, you can select multiple files at once for Insert Pages (meaning you don't have to insert pages from one file then another then another: if they're all in the same directory on the OS, you just select them all at once), just as you can with Combine Files. My apologies if there's something I'm still missing but given that ability to select multiple files at once, I don't see the Insert Pages functionality being any less efficient than the Combine Files functionality.

I'm having the same problem, but Insert Pages gets stuck too, hanging on 'Flattening transparent objects.'

[bencncn]

I'm having this issue 'out of the box'.

I've checked my files and there are no security restrictions applied to them.

Adobe do not provide a way for me to email their support team or create a support ticket within My Adobe regarding this issue.

I think the least they could do is answer this question right here on the public forum.

Perhaps the answer is to use another piece of software. Pity, I paid money for Acrobat.

I have the same problem. I am on Mac 10.7.5 with Acrobat X 10.1.7

I have the same problem. It doesnt matter which files i try to combine, it just wont do it. Can someone help us please? Im in a hurry!!!!!

[Allta Media]

Are you combining files on a network drive? If so, as a test, try moving the files locally to see if the issue still occurs.

[DisasterMan]

Certainly not the case for me - the files are local.

Amazing how Adobe never even fixed this and its Aug 2014.

This is still a problem for me too.  I have been using this feature forever, however, just a month or two ago, it suddenly stopped working and essentially hangs forever on the security point.  I now manually have to insert each doc in order to get them in the right order, which takes about 10x longer.

[Bilbo_Bagels]

Actually @atomicattack it is May 2021 (and no, the problem has not been fixed).

[dmitryb80299766]

It's August 2023...it's happening to me now. Started happening a few months ago and can't get it to stop. Combining TIFF files into a PDF file is nearly impossible now.

I have MacOS 12.5.1, Apple Silicon, Sep 2022 and Adobe still hasn't fixed this issue. Why is that, Adobe?

Architecture: arm64

Processor: Apple M1 Max

Build: 22.2.20191.0

AGM: 4.30.120

CoolType: 6.2.4

JP2K: 2.0.6.50420

For those that have asked, you can do this action without much effort in combining PDFs together. in Preview app on the Mac.

I have just combined 30 PDFs in the correct order and exported it as one PDF.

Here is how you do it:

1. Open the first PDF in Preview.

2. Open the thumbnail view which is a slider on the left that shows the thumbnail pages on the side. (go to View menu to activate it)

3. You can then drag all the other PDF (if they are in named correctly in order of name) into the thumbnail just below the thumbnail of the first PDF.

4. Upon release, the pages of each PDF will be added in the order in which they are dropped in or name of file.

5. Note that if you wish to add the PDFs in a custom order that is not the order of the name of PDFs in your desktop then drag them individually and place them just below the thumbnail of the first PDF.

6. You can then export the file as one PDF.

Hope that helps.

To add, if you are creating a PDF that is not a standard paper size and prefer to keep it that way, instead of exporting, simply just save the file.

I think I came around the solution, here's what I did (and WORKED!), Instead of using the the normal "Combine files into file" wizard, do this:

1. File > Action Wizard > Create New Action
2. In "Start with:" just choose "Combine files into a Single pdf file. Leave the rest of the settings as they currently are. Name the action as you want it.
3. Save

After you created that, run the Action:

1. File > Action Wizard > "Your Action name"
2. If a popup window appear, just check "Don't show again for this action" and then "Next"
3. Choose the files "Add files" > Next
4. Name your pdf and select where you want it to be saved.
5. Done.

Somehow the Action skips the security settings checker not sure why, but it worked for me.

Hope it helps someone! Cheers!

I tried this and still get the following message:

[Test Screen Name]

Seems like a completely different problem: it isn't hanging and it isn't on a Mac. But this may be easier to solve. What is the application that created the document, as mentioned in the message? Is it Word? Excel?

[mike_conventus]

This is on Windows 7 and I am trying to convert Word 2013 in the "Combine Files" tool.  It will convert/merge Xcel 2013 files and PDF files.  I only get the warning with the Word 2013 files.  Thanks!

[Test Screen Name]

Ok. Let's start in Word. Does the Acrobat ribbon show up in Word?

If it shows up, does it work to make a PDF?

[mike_conventus]

Yes the ribbon is there and yes it does make a PDF.
