The dialog (opened via the context menu of the selected items) shows the properties of the selected items B and C. Neither B nor C contain any files or sub-folders (before the creation of D), so the counts (0 files, 0 sub-folders) are correct in my opinion.

With your reasoning the folder dir in test would have to be counted as well, i.e. the dialog should show "9 files, 1 sub-folders" instead of "4 files, 0 sub-folders".

Imagine that "dir/" has 4 files (as in screenshot) that total of 10 mb and files "1,2,3,4,5" are total of 35mb. With the current code the dialog says: "Size: 45mb, 4 files, 0 subfolders" which is totaly misleading. What I want it to show is "size: 45mb, 9 files, 0 subfolders". There is nothing to do with Properties dialog as it calls something like: directorySizeJob->totalSize, directorySizeJob->totalFileCount, directorySizeJob->totalSubdirCount for the size label.

It's called for all the selected items including files.

Simple "size 45mb, 4 files" doesn't represent the truth :)
