[Typo3-dev] user dependant storage of image files

[Michael H.E. Roth]

Hi all,

I have an extension which also allows the BE-Users to upload images. Since 
the BE-Users work on distinct subsets of records of this extension (realised 
by assigning them different sys-folders), I want/need to keep their files 
also apart. My idea was to create a subfolder for each BE-User in the 
extensions upload folder i.e. for user 'abc' the upload folder 
'uploads/tx_extension/abc' and for user 'defg' the upload folder 
'uploads/tx_extension/defg'.
Now my questions:
A) is this possible
and
B) if this is possible, how?

Thanks in advance for all tips and hints.

Michael
