Introduction

Only use this method if encounter issues using Transfer file function on Flow homepage, contact support@partek.com to obtain private key.

The following instructions detail the use of SFTP (Secured File Transfer Protocol) to transfer data to and from your Partek® Flow® instance. SFTP offers significant performance and security enhancements over FTP for file transfers. It also enables the use of robust file syncing utilities, e.g. RSYNC, and is compatible with common file transfer programs such as FileZilla and WinSCP.

SFTP with FileZilla

FileZilla is a graphical file transfer tool that runs on Windows, OSX, and Linux. It is great when needing to do bulk transfers as all transfers are added to a queue and processed in the background. It is possible to browse your files on the Partek Flow server while transfers are active. This is also the best solution when you are not on a computer with command line access or you are uncomfortable with command line operations.

...

Click on the New Site button on the left of the popup dialog.

Type in a name for the connection. Example: “Partek SFTP”.

The connection details to the right need to be changed to reflect the information you received via email. The default settings will NOT work.
