siFS is a filing system that provides access via a serial link to files stored on a SIBO or EPOC computer, such as a Psion Series 5, allowing them to be accessed just like files on a native disc. The standard Psion Link Protocol (PLP) is used; there is no extra software to install or run on the remote machine. It also supports printing from EPOC devices, using either the EPOC or RISC OS printer drivers. Other services provided include clipboard integration and battery monitoring. A plug-in interface enables third-party conversion utilities to be transparently invoked.
