Why am I getting an error message when trying to combine files into one PDF file?

[LBExj]

When I select multiple PDF files and try to combine them into one document, I get a message that "Adobe Acrobat has encountered and unidentified error" and no file is being created. This problem has only recently started as I have been able to merged documents in the past.

Acrobat version? OS version?

[LBExj]

Acrobat DC ... I'm using the Creative Cloud.

[try67]

OS version?

[LBExj]

Windows 7 ... sorry.

[try67]

OK. Does this problem happen with specific files? Try narrowing it down. Merge only two files and see if it works.

Does it work if you attempt to merge the files from within Acrobat (via File - Create - Combines files into a single PDF)? etc.

[LBExj]

I have tried merging various number of documents and have received the same error message. All merged documents have been created using Acrobat DC (via File - Create - Combines files into a single PDF).

Run a Repair Installation from the Help menu.

I ran the Repair Installation from the Acrobat Help menu ... it did not correct the problem.

The problem was not software related.

The files I was trying to merge into a single PDF file were stored in a shared folder on an internal server. These files would not merged into a single PDF. Our working files have always been stored on a server, but only recently have started being a problem merging into a single PDF.

When I copy these files back to the the computer I am using, they merged just fine using Acrobat DC.

Thanks for your help ...

I'm running into a similar problem and believe I have narrowed it down to the length of the file path.  It is not maxing out the OS file path length.  193 character file path will bomb, yet a file in the same location very similar file name except slight shorter, approximately 160 characters, will load combine without error.  Is your issue possibly length of file path?

This solved my problem - thankyou.  Renamed file with shorter name.

I have come to the same conclusion. Though why all of a sudden I'm no longer able to merge files stored on a server, I don't know.

Is there a work around for having Acrobat DC go back to being able to combine files that are hosted on a server?

*(I can open the first file and add them in with the organise pages feature)

I use this feature contantly and don't love the idea of having to move all files I merge from the server to my local machine.

I just bought Adobe Acrobat and installed it on my Mac. I tried to combine files and I got an error message

[try67]

What does it say?

Hello Markb,

We apologize for the inconvenience caused, as per the description above, you are not able to combine PDF files on Mac machine using Acrobat Pro DC, is that correct?

I have checked the records with your current Adobe ID(email) which you have used to sign-in on Adobe forums and found that the subscription of Acrobat Pro DC is canceled and inactive.

You can also check the details of your plan through Adobe.com>Manage Account>Plans and Products, or you can also refer to the Adobe article Manage your Creative Cloud membership

This is the reason you are getting the error message while combining any PDF files as you don't have any active subscription/license if Acrobat. To access the services, you have to subscribe to Acrobat license/subscription.

For plans and pricing, you can refer to Plans and pricing | Adobe Acrobat DC You can also contact Adobe support for the plans and pricing and to place a new order Contact Customer Care

Feel free to update this discussion for any further assistance.

Regards,

Anand Sri.

I have the same issue and I use a Mac but we are current on our subscription. This is what keeps coming up:

[LBExj]

I have narrowed the problem ... I usually create PDF files using the "host" program Illustrator CC. These files will not merged.

I opened the Illustrator files using Acrobat DC and created PDF files ... these files will merge properly.

It must be a problem in the default PDF setting in Illustrator maybe?

I started getting this error message yesterday

- i have full CC subscription

- i updated to OS Catalina i think about 2 weeks ago and it was working fine then

- there shouldnt be a file name length error as i tried it with the files on the desktop but still got an error

- i was able to create a PDF by creating another PDF with the files that didnt combine and then combining both together but i dont want to have to do that all the time

I am also experiencing an error when trying to combine files.

[joeli72053031]

We have an entire team that has the same problem.  Windows 10 - fully patched - new Adobe Acrobat Pro DC, trying to combine Word files, local and network, no difference where they are located.  Makes no difference the size.  We use Office 365 Premium.  All machines are managed by upstream corporation with no ability to disable updates.

There are a few sporadic installs on older PCs with Adobe Pro X that are still able to merge the exact same files from their native network location.  It's just anyone with newer PCs and Office installations that are unable to do so.

Any word from Adobe?

try this we have windows 7 devices with office 2010 - worked for me

Error: No PDF file was created because Adobe Acrobat encountered an unidentified error.

We are having a similar issue.  User tries to combine 10 word documents (Office 2016) in Adobe Pro 2017 on a windows 10 PC.  The first five documents string together and then stops on document 6 and gives error - no application found to open the document.  We resaved the document with a different name, copied the material and saved as new doc with 2 added to the name, converted to pdf - uninstalled Adobe and reinstalled, checked for updates, repaired office.  When using the pdf version to combine the file get error encountered when combining the file message.  The files are saved on a NAS storage device - the user emailed me the files, I saved them to my desktop and the combined with no issue.

We are also seeing an issue for this user when combining files that all seems to combine fine but then when you open the pdf pages are missing or text from one page is missing and a graph shows up on the other half of the page.  These are all combined using documents that were converted to pdf first from powerpoint or excel and look fine - then drop the information when combined.  It is impossible to be able to go back through a 300 page document to make sure every page converted properly.

For what it's worth, I was having this same mystery problem. I was trying to combine ~250 .jpg files into a PDF. It would get to image 130 or so and then start throwing errors. The workaround I used was to make 3 separate PDF's, max of 100 images each (the number might change, I suspect due to available memory?). I then combined those three PDF's with no issues.

Thanks for your reply

I too am able to do that but it makes my workflow slow in having to do that.

We dont pay Adobe the big $$$ for our subscriptions to have to do that.

Its like buying a car that only has 3 wheels. impractical! 😞 

cheers
