Using access lists you can control which users or groups have upload access in specific archives.
Enabling users to upload files to individual archives
When configuring an archive, you can add a user or a whole group to the access list and assign the Upload permission.
This way, you can control precisely who gets to upload files and where they're allowed to submit them.
Presetting a destination folder for upload/copy and move operations to the archive
When you enable users to upload assets to a specific archive you can choose between always placing the file in a preset subfolder in the archive or letting users choose a subfolder themselves. This is set on the Export and Import tab in the archive's properties:
If Default is chosen, assets are placed in the first document folder in the archive. The user is not given a further choice through the user interface.
If User selection is chosen, users must choose both a destination archive and a subfolder inside that archive when uploading assets. They can also create new sub folders as required.
