Q: Very Small Data But Huge Database File Size On MongoDB I have very small database:
> db.stats();
{
    "db" : "oyun",
    "collections" : 29,
    "objects" : 2557,
    "avgObjSize" : 355.83418068048496,
    "dataSize" : 909868,
    "storageSize" : 2410483712,
    "numExtents" : 64,
    "indexes" : 44,
    "indexSize" : 605024,
    "fileSize" : 4226809856,
    "nsSizeMB" : 16,
    "ok" : 1
}

My total database size is bytes but my system.indexes kb ! And total file space consumption is huge ! This database holds holds only near 1 MB data.
> db.system.indexes.stats();
{
    "ns" : "oyun.system.indexes",
    "count" : 44,
    "size" : 3924,
    "avgObjSize" : 89.18181818181819,
    "storageSize" : 2408275968,
    "numExtents" : 20,
    "nindexes" : 0,
    "lastExtentSize" : 630562816,
    "paddingFactor" : 1,
    "systemFlags" : 0,
    "userFlags" : 0,
    "totalIndexSize" : 0,
    "indexSizes" : {

    },
    "ok" : 1
}

[root@guybrush /]#  find . -type f -size +200000k -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'
