Hello,
Thank you for posting in Q&A forum.
Instead of Win32 API, OpenSSH is frequently used in SFTP business scenario. You can use OpenSSH command to connect to SFTP file server and get relevant files.
Or you can directly open browser in Windows and access the SFTP file server to achive same purpose.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best regards,
Jill Zhou
