Are file sizes and formats limited and exposed to users?
Precisions
Front-end operations may require file transfers between the user workstation and the processing servers. The types and volumes of files accepted must be exposed to the user to avoid transfer loads, storage and processing that would be doomed to failure due to non-compliance with expected formats and volumes. Limiting the volume is essential to reduce the impact of transfers.
