+\func{static wxULongLong}{GetTotalSize}{\param{const wxString\& }{dir}, \param{wxArrayString* }{filesSkipped = NULL}}
+
+Returns the size (in bytes) of all files recursively found in {\tt dir} or
+{\tt wxInvalidSize} in case of error.
+
+In case it happens that while traversing folders a file's size can not be read,
+that file is added to the {\tt filesSkipped} array, if not \NULL, and then
+skipped.
+This usually happens with some special folders which are locked by the operating system
+or by another process. Remember that when {\tt filesSkipped->GetCount()} is not zero,
+then the returned value is not 100\% accurate and, if the skipped files were big, it could be
+far from real size of the directory.
