Description: LongFiles is a filing system extension which allows you to use more than ten-character filenames in the standard Acorn desktop. It is transparent in operation, and works with the vast majority of RISC OS applications. For reasons given in the notes, RISC OS machines less than about five years old are very unlikely to need it.
OS Restrictions: Not 32-bit compatible
Languages: {{{languages}}}
Alternatives: raFS, X-Files

Historical Notes

RISC OS has had long filename support since the release of RISC OS 4 in 1999, so this utility would only be needed to read ancient data saved on old-format disks (E or F format or earlier) under RISC OS versions 3.71 and earlier.

Note that if RISC OS 3.1 is being run under VirtualAcorn, it is not affected by the infamous 77-file-per-directory limit. VirtualAcorn uses HostFS and thus supports long file names and unlimited files per directory.

LongFiles works by storing an additional 'hidden' file within each directory, containing the long filename data. This may give long filenames, but it does so at the expense of reducing the total number of files in a directory from 77 to 76. However, even if the long filename data is unavailable (for example, if the LongFiles module was not loaded) files remain accessible with shortened forms of their names. LongFiles is a kludge, contemporary with – and functionally very similar to – the long filename system used for Windows 95. However, LongFiles dates back even earlier, to 1993/1994.
