My system is Ubuntu 20.04 with KDE 5.20.5.
I use Gravit Designer Desktop v.2020-22.214.171.124.
When i save a file (on my computer) or i modify a file, gravit designer
create other file automatic with same name but with extension “.back”.
1º I open gravit.
2º I create a new document.
3º I save file. (on my computer)
4º I draw anything.
5ºI save the file again. Then gravit designer create other file automatic with same name but with extension “.back”.
Also happen if i export a file of Gravit to PDF, JPG, PNG, etc, and i overwrite the destination file because because this already exists before.
I have to be manually deleting the files with the “.back” extension that gravit creates for me automatically every time I modify a design or overwrite an exportation.
