Which option must be enabled for users to collect files through Smartsheet forms?

For users to collect files through Smartsheet forms, the option that must be enabled is the capacity to "Upload From Computer." This functionality directly allows form respondents to select files stored on their local devices and upload them as part of their submission.

When this option is active, users can easily attach documents, images, or other file types directly through the form interface, facilitating a seamless data collection process. This feature is particularly useful in scenarios where additional documentation is required, such as submitting project proposals, testimonials, or any other supporting evidence needed for workflows.

The other options—Link (URL), Google Drive, and Egnyte—do not directly enable file uploads from a user's device in the context of Smartsheet forms. These are alternative methods for incorporating files or references, but they do not facilitate the specific requirement of uploading files directly through the form interface itself. Therefore, for file collection to occur through forms, enabling "Upload From Computer" is essential.
