29. re a degree of experimentation to transfer successfully Translation of DOS and RISC OS filenames Transferring files between DOS and RISC OS is best achieved from within RISC OS itself The DOS partition on your hard disc can be treated just like any other directory simply double click on it to see the files it contains You can then move files between RISC OS and DOS directories as you would move them between RISC OS directories It is important to note the different restrictions that RISC OS and DOS place on filenames however DOS filenames must be in 8 3 format that is a name of up to 8 letters followed by a full stop followed by an extension of up to 3 letters The full stop and extension may be omitted but in practice they rarely are When moving a file from DOS to RISC OS the filename will automatically be changed The full stop in a DOS filename will become a character and the filename will be truncated to 10 characters including the When moving from RISC OS to DOS only the first 8 letters of the filename will be used DOS filenames are not case sensitive and will display in upper case For example the DOS file REPORT59 DOC would become REPORT59 D in RISC OS and the RISC OS file NewReport would become NEWREPOR in DOS 25 Transferring files between DOS and RISC OS 26 There are other characters with special meanings in either DOS or RISC OS These will automatically be translated wh

31. the most effective use of your Risc PC 486 card by sharing files between DOS or Windows and RISC OS rather than treating the two operating systems as completely separate entities There are bound to be tasks which you find are more suited to one environment and you will be most productive if in general you use the method you prefer The attractiveness of the Risc PC 486 card is that it gives you the ability to use both environments cooperatively rather than treating them as two mutually exclusive machines For example suppose you are preparing a spreadsheet for work and you would prefer to create it using a RISC OS spreadsheet application Many of these are able to save spreadsheets in a format known as CSV and most PC spreadsheet applications can import CSV files allowing you to transfer spreadsheets between the two systems relatively easily In general it is possible to transfer most types of data between RISC OS and PC applications so long as a little care is taken to ensure that the data is saved in a format which can be read by the application that is receiving it For this reason it is useful to be able to transfer images text files spreadsheet information etc from RISC OS to DOS and back again This section offers advice on how to go about this It does not provide strict instructions on how to deal with particular filetypes this will depend on precisely what information you are transferring Images in particular may requi
