[digiKam-users] Windows File Properties (such as tags) do not show in digiKam 7.2

[Gilles Caulier]

Hi,

The good news for the future is the official support of ExifTool in the
next 7.3.0 release. We already perform advanced operations that Exiv2
backend is not able to do.

So perhaps this kind of problem can be done in digiKam directly without
using ExifTool CLI directly.

Feel free to open a file in bugzilla about this topic for future
integration.

Best regards

Gilles Caulier
