[Typo3] Problem with a directory ending with a "."

[Juha Sipinen]

I created a directory inside TYPO3 (File -> Filelist), a directory that ends
with a period (.)
 
The directory is "Milk_Inc."
 
Now the problems are:
 
1. I can't upload files into it because it says "Target was not a
directory!"
 
2. I can't rename it because "Target
"/var/www/public_html/fileadmin/Milk_Inc" was neither a directory nor a
file!"
Note that the error message displays it WITHOUT the "." character.  However,
my FTP program proves the directory is there with the "." character.
 
3. I can't delete it inside TYPO3 because "Target seemed not to be a
directory! (Shouldn't happen here!)"
 
4. I can't remove it with my FTP program because TYPO3 software now owns the
rights to the "Milk_Inc." directory.
 
 
So, what can I do to get rid of the directory?  There should've been a
warning NOT to make a directory ending with a period.  There can be "."
characters in the middle of the directory name but NOT as the last
character!
