Your account may not be active or locked out. Also check with FINRA support team to check the status of the account and it has correct privileges to use fileX services.

As mentioned in this document, fileX service access is controlled by credentials provided and permissioned by FINRA Entitlement services. Please call FINRA support at 800-321-6273 or visit the web page at https://tools.finra.org/cc_support/ to request access. You may also check https://www.finra.org/industry/entitlement-program for information related to Entitlement process.

fileX service with FINRA is tested with some SFTP clients like FileZilla, SecureFX and WinSCP.

Both sessions will see the same directories and files. fileX service moves the file(s) immediately after the upload is complete, so a file that gets uploaded in session ‘A’ may "disappear" from view of session ‘B’.

SFTP and AWS S3 Direct transfer methods do not have any limit on the number of files that could be transferred in a single operation but HTTPS REST method allows only ONE file per API call.

fileX does not allow rename or delete operations on files at the download locations.
