The correct answer is C. 100 . According to Relativity’s official Simple File Upload documentation, the SFUMaxFilesToUpload instance setting determines the maximum number of documents a user can upload at one time using Simple File Upload. Relativity states that administrators can configure this setting up to 100 files , and when the setting is at its maximum, users can upload up to 100 files at one time . If a user selects more than 100 files, Relativity uploads only the first 100 selected files and does not upload the remainder. Relativity also indicates that a warning message appears in the upload window when more than 100 files are selected.

This makes the answer operationally important for administrators because Simple File Upload is designed for lightweight, direct document uploads within a workspace, not for large-scale ingestion jobs. For more substantial data loading exercises, administrators typically use Relativity’s broader import workflows rather than relying on Simple File Upload. From an RCA perspective, knowing this limit helps with user support, upload troubleshooting, and setting expectations for workspace users who need to add small batches of documents quickly. Therefore, among the options given, 100 is the only choice that aligns with the official Relativity behavior for Simple File Upload.
