  Delete file which is possibly not closed.



  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.
