-  --d - <-i directory_to_search> [-e exclude_directories = ""] [-s min_size = 1024] [-x allowed_extension = ""] [-l type_of_search = "hash"] [-delete = all_] - search for duplicates files
+  --d <-i directory_to_search> [-e exclude_directories = ""] [-s min_size = 1024] [-x allowed_extension = ""] [-l type_of_search = "hash"] [-delete = "aeo"] - search for duplicates files
     -i directory_to_search - list of directories which should will be searched like /home/rafal
     -e exclude_directories - list of directories which will be excluded from search.
     -s min_size - minimum size of checked files in bytes, assigning bigger value may speed up searching.
     -x allowed_extension - list of checked extension, e.g. "jpg,mp4" will allow to check "book.jpg" and "car.mp4" but not roman.png.There are also helpful macros which allow to easy use a typcal extension like IMAGE("jpg,kra,gif,png,bmp,tiff,webp,hdr,svg") or TEXT("txt,doc,docx,odt,rtf")
-    -k type_of_search - allows to use fastest which takes into account only size, and more accurate which check if file contnet is same(hashes).
-    -delete - removing file except one.
+    -l type_of_search - allows to use fastest which takes into account only size, and more accurate which check if file contnet is same(hashes).
+    -delete - delete found files, by default remove all except the most oldest one, it can take arguments: aen(All except newest one), aeo(All except oldest one), on(Only one newest), oo(Only one oldest)
     Usage example:
-      czkawka --d -i "/home/rafal/,/home/szczekacz" -e "/home/rafal/Pulpit,/home/rafal/Obrazy" -s 25 -x "7z,rar,IMAGE" -k "size" -delete
-      czkawka --d -i "/etc/,/mnt/Miecz" -s 1000 -x "VIDEO" -k "hash"
-      czkawka --d -i "/etc/" --delete
-  --e - option to find and delete empty folders
