    Hi all
    Sorry if this is a silly question. However hope someone can answer. If I have a sd memory card and have erased it with disc utility and set it as a mac os extended (journaled) format. Will any files I place on this card be viewable or playable on a windows or a smartphone?

    thanks in advance

    No to both. Without add on software, Windows won't read a Mac formatted disk. I am not aware of any smartphone either that will read a Mac (HFS+) formatted disk.

    you will need to use FAT mode if you want it to be read by windows and mac.

    the only real limitation of FAT is a 4GB individual file size.
    There may be some limitation on the newer large drives (bigger than 2TB) but i'm not sure, but I'm guessing your memory card doesn't come anywhere close.

    smart phones should also be able to read FAT.

    If you have files bigger than 4GB each, you need to use...
    NTFS - Windows native
    HFS - OS X native

    with add on software you can read the other format (so read NTFS on a mac).
    not sure if phones will handle NTFS, check your manual.

    if you're running android, i just did a quick google search for "NTFS Android" and came up with this, not sure how well it works, but it will let you read NTFS and HFS on android.

    Windows Vista/7/2008/2012 and Mac OS X will both read exFAT with an individual file size limit of 16EiB.
