RISC OS filetype database unveiled

Giv'us yer details

One thing about RISC OS that makes it different from other OSes is the way it handles file types. Just about every file created by a RISC OS application has its own unique file type, allowing users and software to immediately recognise a file and what its contents should be. File types are stored as a 12 bit number along with other file information like the file name and size. Software authors can give RISC OS file type names, allowing the user to set a file's type as "Sprite" rather than having to use the file type code (&FF9 in this case).

Before an application can officially use a filetype, it has to be registered and allocated by contacting allocate@riscos.com. This is a service still running from the Acorn days and up and till now, the lists of registered filetypes has been kept extremely confidential to avoid leaking details of unreleased software. Now as part of RISC OS Select, RISCOS Ltd., would like to introduce a public file type database so users can enter a file type and find out what applications handle it and the availability of said software.

"Our desire is to make the database of filetypes as complete as possible, and to that end we need to know if anyone has registered filetypes with Acorn in the past that they do not wish published for whatever reason", states the RISCOS Ltd. press release. "We are also aware that there are apparently a couple of Registered filetypes where the same filetype number is being claimed by different developers."

So, if you have registered a file type, contact RISCOS Ltd. to either confirm that you would like your filetype to go into the public database or to inform them that you don't want your filetype information to be publish. More information is given from the link below.

"Obviously this is a good promotional opportunity for all developers and we hope that everyone will provide the above details as soon as possible", RISCOS Ltd. conclude.
