    I was doing a backup ready for a new ROM or mods to this current one and part way through it said "SD-ext not found. Skipping SD-ext"
    What is it and is it important?? I've done hundreds of backups and not seem this come up before so I don't want to do anything incase I can't restore if it goes wrong.

    EXT is a file system for your sdcards. Usually your sdcard is entirely composed of a FAT partition, but you can repartition the card to give up some space to an extra partition.

    When custom roms detect that partition, apps2sd kicks in and all your apps run from that partition rather than tthe phones memory, allowing more apps to be installed. (This is a older but more powerful form of apps2sd than the official Froyo/Gingerbread apps2sd).

    Its normal that you see that message.

    Thanks Xyro :)

    I wonder why it hasn't come up before. Oh well, if it's nothing to worry about then I'm not worried :)
