Upload Instructions

Upload your file to the folder assigned to your organization. If you are unsure which folder to use, contact CTData Collaborative staff before uploading.

If you need to submit a corrected version of a previously uploaded file, upload it with the same file name. The system will automatically version it (v_2, v_3, etc.) and retain earlier versions for audit purposes.
