[support] extended upload modul?

Hello all,

I'm fairly new to this mailinglist and Drupal. I administer a community website where we need advanced functionality with file uploads:

1. we want to have a possiblity for easy uploading files, without creating content. 2. allowed user should be able to browse the content of the upload folder. 3. it would be nice to have the possibility to create a folder hirachy to sort the files into categories 4. a interface with the version control system bazaar? would be nice to have :-).

I'm not sure if the normal upload modul can do all of this? Are there some other moduls that extend the upload functionality of Drupal?
