Windows11 - Trouble with LargeFileSupport on 5.5GB PDF File

[silligoose]

I have downloaded version 12.97. exiftool and exiftool_files directory are colocated. In one of the topics it is mentioned that starting 12.88 LargeFileSupport is on by default. I tried with the flag and without. Getting same error.

Code Select Expand

exiftool -api LargeFileSupport=1 -copyright="aa" testpdf_small.pdf
    1 image files updated
5.5GB file

Code Select Expand

exiftool -api LargeFileSupport=1 -copyright="aa" testpdf_large.pdf
Error: Huge files not yet supported - testpdf_large.pdf
    1 files weren't updated due to errors

exiftool -copyright="aa" testpdf_large.pdf
Error: Huge files not yet supported - testpdf_large.pdf
    0 image files updated

Not sure what I am missing.
Thanks for the help

You're not missing anything.  Supporting large offsets for PDF files requires some specialized programming -- it will need a different format for the PDF cross-reference stream.  Expect ExifTool 12.98 to include support for these files.

Thanks Phil for your quick response. When are we expecting 12.98 release?
If there is a pre-release version, i would be happy to verify large file support for pdf.
Thanks

Here you go, a 12.98 pre-release: exiftool-12.98p_64.zip

The official release is probably a couple of weeks away.

... and just to complete the test, did you try reading the resulting PDF with other software?

Ran with few more files that were failing. All succeeded.
Read values back using exiftool and Adobe acrobat. Works great!!.
Thanks
