+  This function is intended to be used exclusively as a temporal solution
+  for Win NT in case when it is needed to delete a not closed file (note
+  that the file must be opened everywhere with FILE_SHARE_DELETE mode).
+  Deleting not-closed files can not be supported on Win 98|ME (and because
+  of that is considered harmful).
+  
+  The function deletes the file with its preliminary renaming. This is
+  because when not-closed share-delete file is deleted it still lives on
+  a disk until it will not be closed everwhere. This may conflict with an
+  attempt to create a new file with the same name. The deleted file is
+  renamed to <name>.<num>.deleted where <name> - the initial name of the
+  file, <num> - a hexadecimal number chosen to make the temporal name to
+  be unique.
