[REQ] Please modify the default button in delete dialog [#21459]

[lucasb]

Please modify the default button in delete dialog box from [Yes] to [No].

Due to several issues with the file tree when deleting/renaming folders I think that the default selected button might me [No] to prevent accidentaly files/folders deletion.

Greetings.
