This is available for Authors.
In Inspera Assessment, all question types can contain inserted files. When a file is inserted into a question, it becomes available to the candidate for downloading through a link.
If all file types are selected, then the Author can upload any file type. If it is not listed in our internal supported types, it will be downloaded with a .dta extension, which the user can then manually modify.
To learn more about the security concerns associated with SEB and certain file types, visit the Help Center article SEB Options for Computer Labs.
