How can I change all PDF links (absolute and relative) to new absolute links in bulk?

I have an Endnote library (Library.enl) with around 1000 entries. Some enties have absolute PDF links, such as C:\OldPath\File1.pdf, C:\OldPath\File15.pdf, and some have relative PDF links, such as FIle23.pdf, File158.pdf. How can I change all PDF links (absolute and relative) to new absolute links in bulk, such as D:\NewPath\File1.pdf, D:\NewPath\File15.pdf, D:\NewPath\File23.pdf, D:\NewPath\File159.pdf? I am happy to edit the Library.enl file manually, please help me how. Thank you.

I believe you can only change absolute to relative quickly and easily.  There is no automated way to move relative saved PDF to a new location in bulk within endnote and retain a link.    There is a thread from a few years ago discussion some trials, but I don’t think they came to a solution.  You can look at that thread here.  

You can do it with AppleScript.  I’ve pasted below a script I wrote that you can use as a starting place.  Obviously, it will take some modificaiton.  Also, I wrote it early in my AppleScript learning, so it is pretty ugly in terms of how I coded it.  I hope it is helpful as a start.

-- Verion of 121026
-- Renames the attached full document of the selected EndNote record to the form "Jones_1996_114", where 114 was the record number
-- It is horribly ugly and specific to the author, but should be easily adjustable for others.

Thank you for the reply. How could I run AppleScript on Windows 8 machine? Is there any similar script for Windows?

Oh!  My bad, entirely.  I happen to work with almost entirely Mac users and just didn’t stop to think that you might be on a Windows machine.  My apologies.  The answer is, unfortunately, “I don’t know if there is an equivalent in Windows EndNote.”

I am just posting this, if someone is interested in it…I recently had to change computers and the new computer required all my data to be in a specific folder that was different than my old computer’s data folder.  Consequently, all my absolute links to pdf reference files did not work but I was able to fix it in bulk.

For the purpose of demonstration: My old computer’s data file directory was C:\Olddata and my new computer’s directry is C:\Newdata.

Open your EndNote (I have version X9) library that you want do fix. Select File>Export>Save as type: XML; uncheck Export Selected References; select a temporary location; Save the file.

Close the library in EndNote

Open the temporary location. Right-click on the exported .XML file and open with NotePad.

Replace> All> C:\Olddata with C:\Newdata

Save file (it will automatically saved as a .txt file)

Return to EndNote.

Create a new blank library by File>New>Give in name and a desired location

Select File>Import>File…> Select your import file (the .txt file); Import Option: EndNote generated XML; Import the file

The new library is filled with the references from the old library with updated absolute links.  All our reference fields are transfered.
