The new data center server at BKG runs a so-called "event manager" 
and moves the incoming files as soon as the ftp-upload is 
completed. In order to allow users to check the uploaded files,
if they like to do so, the event manager ignores now the filenames 
that start with "_", e.g., "_WTZR2100.05D.Z". 

Users may upload data files with the prefix "_", check the files
as they want to do and then rename the files. A corresponding
procedure could look like follows:

....
put wtzr2100.05d.Z _wtzr2100.05d.Z
ls _wtzr2100.05d.Z
rename _wtrz2100.05d.Z wtzr2100.05d.Z
...

The file will then be moved after "rename" immediately. 

Please note: This approach will cause a small additional delay in
the data transfer and it is not requested from our data center. You may
decide by yourself.

Some users that upload data to BKG send a complementary "*flg" - file,
which indicates that the file upload is now finished. From
our point of view it is no longer needed, because the end
of ftp is now checked by or event manager. But on the other hand 
flg-files cause no problems for our system.
