The File upload options are: * **Require a response:** Toggle on/off to require respondents to submit an answer to this question block * **Accepted file types:** Enter file types accepted in the survey. If the survey only accepts document files, include docx, pdf etc. If all file types are accepted leave blank. * **Short block label:** Specify a concise name for the block title, used in tables and charts as a reference for long block titles to improve readability where space is limited. * **Disable Text analysis:** Toggle on/off to enable/disable text analysis for the block * **Visible to admins only:** Toggle on/off to make this block and its responses visible only to project admins. If response publishing is enabled for the project additional options are: * **Hide answers on publish:** Toggle on/off to hide/show uploaded files being visible in published responses. * **Hide the transcript on publish:** Toggle on/off to hide/show any accompanying text-based transcript of uploaded files in published responses. * **Hide the download link on publish:** Toggle on/off to disable/enable the option for others to download uploaded files from published responses. * **Title when published:** Specify a custom title for this block in published responses (if you'd prefer something other than the default survey question title). **Tip:** File uploads in surveys are limited to **100MB** per file. Consider adding a note like, *“Please ensure files do not exceed 100MB,”* to guide respondents and prevent upload issues. File Upload screenshot: to guide respondents and prevent upload issues.
