I see that you used Google translate to translate it to German, and then translated the German text back to English. In this case that's not an improvement of my original text. Was it by accident?
My original text was this:
When using the "Only files of this type" field, Total Commander unselects pre-selected files that are successfully copied, while files excluded by the filter remain selected for further actions, such as copying with a different filter or to another location. Pre-selected folders remain selected if completely skipped by a filter (e.g., "| somedir1\"). However, folders are unselected when processed, even if no files inside are copied (which can feel unintuitive as it suggests no further action is needed).
One other minor consideration is this. When I wrote "However, folders are unselected when processed", I meant when processing a folder has finished. I see that you can read it two ways, and that it was translated in the other meaning to "Ordner werden jedoch bei der Verarbeitung abgewählt". This is not entirely correct and could be fixed by changing "bei der Verarbeitung" into "nach der Verarbeitung", and for English by changing "when processed" into "after processing" (that is, if you keep my original text, which is what I recommend).
