The Upload file field allows users and survey participants to upload up to 5 MB.
It is possible to upload larger files (up to 2GB per file) by purchasing the Large File Upload feature for your study.
All file types are accepted, except executable files and SVG image files.
Please note that at the moment, it is only possible to upload one file at a time.
Here is an example of the 'Upload file' field, shown in a study form:
Once a file has been added to the field, a download button is shown below the file, with which the uploaded file can be downloaded.
For image files and PDFs, there is also the option to view the file without downloading:
If the uploaded file needs to be removed or changed:
- Use the 3-dot menu
- Select Delete upload to remove the file.
Once cleared, you can add a new file.
Please note:
- It is possible to download files with View permissions only.
- You can download the files by exporting the data study from Castor.
