I discovered KDE makes backups in a folder : “ … \AppData\Roaming\kdenlive\.backup”
In this folder are 729 files !!!
It is filling this directory with files since the first day I started using KDE. It even keeps backups of projects I have deleted from disk long time ago. Within a few years my hard drive will be full.
How can I prevent KDE from doing this or delete them when I close the program or after a few days or weeks ?
