In the 'EDIT' - 'Questionnaire' tab, you can also insert the question type 'File upload' in your survey, where the respondent can upload their file to the survey. Open the menu on the left side or click on the "Add question" button at the bottom of the questionnaire, then select 'File upload' from the 'All Question Types' drop-down under 'Standard Input'. Enter the text of the question and adjust the settings if you wish.
Additional restrictions for respondents when uploading a file:
- the maximum allowed size of a file uploaded by the respondent is 16 MB;
- allowed file types are: "jpeg", "jpg", "png", "gif", "pdf", "doc", "docx", "xls", "xlsx";
- a maximum of 4 input fields is allowed in an individual question, i.e. a maximum of 4 files that the respondent can upload for one question.
The respondent can remove the file they uploaded and upload another or leave it blank. In analysis and data, the file is saved as a link (URL) to the file. The survey editor has the option to edit the link (delete or replace it).
