What is on an Android external sd card?

    This is for a Samsung Galaxy S3 (belonging to a family member) that has begun to run slowly, losing charge quickly and sometimes getting very hot when seemingly doing nothing.

    I am a mobile phone/Android newbie, but guess that the cause might be shortage of space on the fixed internal memory and the the external SD card.

    Internal memory: total 11.25GB available: 1.74GB. I can account for this. Memory Manager apps, e.g. My Files, show that 95% of the space are video and pics taken by S3 camera. I will delete these after backing them up onto a PC. No problem with that.

    But I don't understand how the space is used on the
    External SD card: total 14.83GB available: 10MB

    There is about 1GB of jpg pictures in /DCIM/Camera folder. The rest

    .downloadTemp folder No files
    .spotlight-v100 folder Store-V1 file message 'No apps can perform this action' when clicking (to Open)=M
    folder Store-V2 files with message M when clicking
    .temporaryItems Folders501 message M for the files
    .Thrashes folder 501 message M for the files
    Android folder with subfolders but No files
    DCIM folder with Camera folder with about 1GB of jpg files
    LostDir folder No files
    Many files message M when clicked

    I don't understand.

    Q1. Is there an app or some other way to get the sizes of all folders and files on the SD card? (so that I can check that all parts add to 14.83GB)

    Q2. Is there a way to verify the SD card is healthy and all of it can be used, i.e. that there are no 'bad sectors/sections' on it that no longer can be used (and that may or may not be included in the space statistics)?

    Q3. In Android Settings there is a (re)format SD card command. I assume this command reformats the external SD card (ExtSdcard) and not the internal memory referred to as sdcard0. Shall I use this?

    Q4. I think, but am not sure, the external SD card can also be reformatted from a PC via a USB data cable.
    If so, is this better/worse than reformatting from Android Settings?

    Q5. Where can I read more about what is on Android external SD cards?

    At some stage, that card has been used in a Mac, hence the .spotlight and .trashes files etc.

    Reformat the card, but ensure that your photos are backed up elsewhere first as reformatting will wipe everything on the card. The reformat command within the phone will relate to the 'external' SD card.
