Opening RTO files

Have a problem opening a .RTO file? We collect information about file formats and can explain what RTO files are. Additionally we recommend software suitable for opening or converting such files.

What is the .RTO file type?

Primarily, the .rto extension's association belongs to the Rumba File Transfer Profile (RTO) file type/format. Rumba is an advanced terminal emulator and system administration kit for IBM eServer iSeries/System i (formerly, AS/400) mainframe machines by Micro Focus (formerly, NetManage). A mainframe is a powerful and failure-proof server, core of a corporate computing network or cluster.

There are mechanisms to handle the exchange of files between IBM iSeries mainframe machines and PC's. RTO is one of the transfer request formats used for that purpose.



A PC .rto file is basically a text-based file transfer profile with INI-like syntax to control an information transfer session between an iSeries/System i mainframe and a personal computer over a network. RTO files are often used together with BTF batch files to enable unattended batch transfers.

Although considered legacy, RTO transfer profiles can still be opened and used with the IBM iSeries (System i) Access utility for MS Windows.


Alternatively, the .rto extension is used to denote the GeoView Rational Function (RTO) file type/format. RTO is an XML-based format used in GeoView, a well-established and internationally-recognized cartography system developed by IGN France. A GeoView .rto file is a plaintext file that contains structured tag markup in accordance with the GeoView XML schema.
