actually this feature is already part of the TWG Flash Uploader
. But in TWG not used and "only" folderbased.
As a first step that is quite easy is simply to add a quota to a folder. this can be easily checked by the Uploader.
What you can do:
open the tfu_config.php's in admin and i_frames.
and there you can set a $directory_file_limit
.
btw. this only work in the registered version because it's a features of the flash
.
then you already have a restriction for one folder. If you disalow your users to create directories you have a limit
.
And you should only let the users use the frontend upload because in the twg Admin you can switch to the html upload that does not do this check.
