    I have Windows XP Pro, SP2.

    When I total up the size of all the files in the Thunderbird folder in Windows Explorer it comes to about 285 M. But when I check the amount of usage using Computer Management/My Computer after I transfer the Thuderbird folder to an SD Card I get about 700 M. Can anybody tell me what's going on here?

    You are comparing the size between that of the Disk drive and that of the SD card??

    The difference could be due to the differences in cluster sizes.

    Find a "tiny" file (or create and empty TXT file) on both and then do right mouse, properties.
    Check the "size on disk" which will tell you the cluster size.

    For NTFS the cluster size is 4K, so a 1 byte file will take 4K on disk.
    If the SD card has a cluster size of 16K, then a 1byte file will take up 16K of space.
