Can't open a dxf file from Windows Explorer any more (just updated LibreCad).

Windows11, all updates installed automaically.
In Explorer: doubleclick file with .dxf extension.
Opened window: 'pick an app', showing as first choice LibreCAD (with wrong icon), showing at the bottom choice 'only once', not showing the normal choice 'allways'.
Clicking LibreCAD (with wrong icon), no result (window stays).
Scroll to 'pick an app', pick LibreCAD > LibreCAD.exe (with right icon).
Back to window: 'pick an app' as shown before.

How to link .dxf to LibreCAD again?

Settings > Apps > All apps shows LibreCAD.
Settings > Apps > Standard apps doesn't show LibreCAD.

just in case - are you able to open the same dxf file directly from LibreCAD (i.e - open it form File->Open menu).

And which version of LC do you use?

We need to associate the ".dxf" extension with the application.

Fixed in the 2.2.1 branch, and will be available in the next 2.2.1.4 release.

To test the latest 2.2.1 build:

LibreCAD (installed 15-2-2026)
Version: v2.2.1.3-2-g1598766fb
Compiler: Microsoft Visual C++
Compiled on: Jan 11 2026
Qt Version: 5.15.2
Boost Version: 1.87.0
System: Windows 10 Version 2009

I can use File > Open and click through the folders to my project, which is a nice work-around.
I can even use File > Recent Files, and it shows even files from before the update.
Still, I'd like the link back.

I now have LibreCAD
Version: v2.2.1.3-6-g98fea285b
Compiler: Microsoft Visual C++
Compiled on: Feb 15 2026
Qt Version: 5.15.2
Boost Version: 1.87.0

I've got the link back! Thank you!
