[ExtendScript] File.displayName no longer supported in ID 20.4 macOS

In many — and perhaps all — circumstances, the displayName property of both File and Folder instances will just return an empty string in InDesign 20.4 macOS. (Needless to say, this bug is of unprecedented severity and is already causing countless script breakages.)

    Tested along: And yes, displayName was broken with InDesign 2025 v20.4.0.52. Returned empty string.

    It seems ok with InDesign 2025 v20.3.0 and Prerelease InDesign 2025 v20.4.1.3.

     

    Still, I have no idea what happened when I got "Volume" as result before.

    Sorry for any confusion…

      Hi Marc,

      in one occassion, a text file saved with TextEdit App displayName returned the string "Volume".

      However, with fullName all went ok.

       

      Tested with the same result with:

      InDesign 2025 v20.3.0 and InDesign 2025 v20.4.1.3 on macOS 12.7.6.

       

      Will test on other properties of the file as well …

      Hm. A second test with InDesign 2025 v20.3.0 revealed the right string with displayName.

      Will test on…

        Hello @Marc Autret,
        Confirmed: In InDesign 20.4 on macOS, the displayName property for File and Folder objects often returns an empty string, breaking scripts that rely on it. This appears to be a regression and has been reported by multiple users. Until Adobe issues a fix, consider using name or fsName as temporary workarounds. Stay tuned to Adobe’s known issues page  for updates.


        Best Regards,
        Clark Dahl

        Many things seems to be broken in this version. Reports of plugplug library load also has issues then Folder.execute is also reported to be not working. I am thinking if there are rarely any fixes done on the ESTK end how come so many things broke in this build

        I confirmed your findings Marc, also using ID 20.4 MacOS.

         

        Side note: I stopped using `File.displayName`, in favour of the more verbose `decodeURI(File.name)` years ago when I noticed back then that some files just don't have a displayName. I never looked further into it but I assumed that some file systems just don't write it.
