Created attachment 155401 [details] Error message shown SUMMARY Modified PDF files (e.g. after inserting a signature) cannot be saved when opened from an UNC path of a share (\\servername\sharename\exampl01\document1.pdf). An error message is shown (sorry for the translation, original language is German): "File kan not be saved in file 'file://servername/sharename/exampl01/document1.pdf'. Error 'Partfile //servername/sharename/exampl01/document01.pdf' cannot be renamed. Please check permissione. Try a different location." It will be saved without any error though when the same PDF file has been opened from the same share as a mapped drive (K:\exampl01\document1.pdf). STEPS TO REPRODUCE 1. Open a PDF from an UNC path. 2. Add a note or signature to the document 3. Save document with CTRL+S OBSERVED RESULT Okular outputs error message, stating: "File kan not be saved in file 'file://servername/sharename/exampl01/document1.pdf'. Error 'Partfile //servername/sharename/exampl01/document01.pdf' cannot be renamed. Please check permissione. Try another location." A part-file containing the changes is created but renaming into the original file name fails. EXPECTED RESULT Okular save the PDF without error, just the way it does when the document is opened from within a mapped network share. SOFTWARE/OS VERSIONS Windows: 10 Pro
