Just tested on a kubuntu desktop, and there's a checkbox option in the save dialog that reads "Automatically select filename extension (.docx)". See attached screenshot.
Predictably, if I check this option, the extension is automatically added to the filename, and if I uncheck it, it's not. Were you expecting a different behaviour? Or are you not seeing that checkbox? ** Attachment added: "Capture d’écran du 2019-01-17 17-14-44.png" https://bugs.launchpad.net/df-libreoffice/+bug/1812101/+attachment/5230005/+files/Capture%20d%E2%80%99%C3%A9cran%20du%202019-01-17%2017-14-44.png ** Changed in: libreoffice (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1812101 Title: libreoffice-kde5 file dialog/picker doesn't add extension automatically Status in LibreOffice: Incomplete Status in libreoffice package in Ubuntu: Incomplete Bug description: Description: libreoffice-kde5 file dialog doesn't add automatically the file extension which are important for.docx .xlsx, otherwise the system recognize them as zip.
