SUMMARY


STEPS TO REPRODUCE
1. On Windows 10, install Okular from Microsoft Store (the latest version available at Microsoft Store is 1.11.1).
2. Try to open a PDF file with Okular where the path with the filename is very long, more than 260 characters (such as "D:\Users\joaop\OneDrive\Documentos\Adv\Admmetta\___revisadas\28366–26.2012.811.0041 Neurotech Centro de Formação e Aperfeiçoamento; Hernan Escudero Gutierrez; Marcia Regina de Oliveira Gutierrez\90-90v 2014-08-04 Tentativa de citação e provar propriedade de bens.pdf".
3. Try to open the file with Mozilla Firefox 83.0.

OBSERVED RESULT
Okular says it could not open the file whose filename and path exceeds 260 characters while Mozilla Firefox opens it normally.


EXPECTED RESULT
Okular should open the PDF file even if the filename and path exceeds 260 characters.

SOFTWARE/OS VERSIONS
Windows: 10, version 20H2

not 100% sure it's kio's fault, it may also be path handling inside poppler, needs someone to have a look.

Hi Sir,

I am also facing the problem of long path name exceeded 260 chars. Just wondering if there is a solution found for this problem? 

A solution will be appreciated.

Thank you very much.
