Funny enough, I discovered this a couple of weeks ago when I extracted a zip file with the top option and I had like 100 files all over my downloads directory. I was so pissed I had to delete them all one by one and make sure that I don’t delete the files that I actually want there. It was so painful. Then looked at the bottom one and it made sense and it was an “aha I fucking love kde” moment.
Doesn’t Ctrl+Z undo the extraction? I may be dreaming, but I remember there was a fast option to delete all the files extracted. Anyway, we already know about autodetection B)
