IDEA: Batch merge many pdf (result : only one big pdf per subfolder)?

(1/2) > >>

jity2:
Dear all,

I need to merge many pdf files located into thousands of subfolders (several levels) full of pdf and other files. At the end, I need only one big pdf file per subfolder.


Example: “C:\Main_folder\” contains :

C:\Main_folder\subfolder_wgs\jshhd545.pdf

C:\Main_folder\subfolder_wgs\jshhd545.htm

C:\Main_folder\subfolder_wgs\ejkehe5485.pdf

…

C:\Main_folder\subfolder_ghdfdhd\jdjdhjd5545.pdf

C:\Main_folder\subfolder_ghdfdhd\jdsdjdh44.pdf

…

C:\Main_folder\subfolder_yuege255\uejgd56564\kdfhk5465.txt

C:\Main_folder\subfolder_yuege255\uejgd56564\kdfhk5465.pdf

…etc..

Desired results:

C:\Main_folder\subfolder_wgs\subfolder_wgs.pdf

C:\Main_folder\subfolder_ghdfdhd\subfolder_ghdfdhd.pdf

C:\Main_folder\subfolder_yuege255\uejgd56564\subfolder_yuege255.pdf  (or C:\Main_folder\subfolder_yuege255\uejgd56564\uejgd56564.pdf)

etc…



note: It would be great if results could be added into a new big folder (like C:\Main_folder2\ for instance).

I am on Win8.1 64bits.
Free or open source solutions preferred.
Thanks in advance ;)

Something along these lines?

jity2:
Thanks "4wd". ;)

I had some difficulties (virus or hammering websites) finding the correct programs that you have recommended files in the thread (https://www.donationcoder.com/forum/index.php?topic=40103.msg374877#msg374877) but I finally found a work around with these links :
http://filehippo.com/download_universal_extractor/4795/
http://web.archive.org/web/20140315000000*/http://www.adultpdf.com/products/txttopdf/txttopdf.exe
https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/pdftk_free-2.02-win-setup.exe
Universal extractor did not work with pdftk but I was able to find the correct file once I installed PDKtk in : "C:\Program Files (x86)\PDFtk\bin\".

So anyway I was able to test your solution. It works correctly for one folder. ;) I hope you can adapt it to subfolders. ;)
Note: the header is not really needed for me but please do as you prefer. ;)

Thanks in advance for you help ;)

PS: in my case I don't have password protected pdf files but if someone has some you can remove them using the shareware "PDF Password Remover v3.1" http://www.verypdf.com/app/pdf-password-remover/password-remover-com.html using these instructions :
In windows find the "command prompt" then copy/paste the following (just adapt the correct path C:\...\) :
for /r "C:\test\" %F in (*.pdf) do "C:\Program Files (x86)\PDF Password Remover v3.1\pdfdecrypt.exe" -i "%F"

Yes, probably need to update the innounp binary for UniExtract, I run a more updated version than what is available on the original site along with updated extractor binaries.  You can get it here, (17.51MB - link will expire in 72 hours).

I hope you can adapt it to subfolders. ;)

Should be easy, I'll have a play around.

Requires the files from PDF Toolkit either extract them from the setup file using UniExtract or install it and then copy the files into the same folder as the script, (then you can uninstall it).

So your folder will look like this:

IDEA: Batch merge many pdf (result : only one big pdf per subfolder)?

Run jsPDFt.ps1 using the shortcut.

Hopefully it'll work - it did here.

NOTES:

* No provision for password protected PDFs, it'll probably die a horrible death while running if it finds one.
* No provision for seeing if the output file already exists, if it does it will probably be overwritten.
