    Hi,

    I'm trying to remember if there is a limit to the number of files a
    directory can hold in R Adjust 4.39. Don't think I've got a guide here
    in the Antipodes.

    Is that on VRPC?
    If so, which filing system are you using?

    Yes.

    Eh? I didn't know there was a choice. Aeeons ago I just got my shiny CD
    from Aaron and set it up as per instructions.

    Ah! I think I see what you mean. It's RPC-StrongArm Adjust. Long
    filenames are OK.

    On Filecore formatted storage directories can grow to accommodate more
    files until they reach 4MB. The number of files will depend on the
    length of the filenames, the 28 bytes of meta for each file, and another
    ~36 bytes overhead.

    I believe the 'old' formats were:
    S/M/L: 47 files per directory (BBC Master)
    D/E/F: 77 files (D = Arthur, E = RISC OS 2, F = RISC OS 3)

    and it's the 'F+' format that allows 'unlimited' files (and >10 char filenames), up to the limits you cite.

    Everything recently formatted will be F+, but some old discs (old
    floppies?) may be E or F with the old limits. IIRC there is no difference between E or F when formatting hard drives, F was just introduced for 1.6MB
    HD floppies as against 800KB E-formatted floppies.
