Assumptions and Constraints
- Maximum file size is 5Mb. The size is configurable and can be changed based on the business need.
- There is no restriction of file type/extension in HyrbidChat. It is also configurable based on the business requirements.
- Uploaded files can be stored indefinitely on server if required. Time limit for file storage on server is dependent upon the space requirements for the business deploying the HyrbidChat solution.
- For downloading media, only filename needs to be specified. Example is available on Expertflow Public Workspace.
