StringformatSize(long size, boolean forceFixLen, boolean forceSizeInBytes)
format Size 
StringBuilder buf = new StringBuilder(64);

StringformatSize(long sizeInBytes)
format Size 
double displaySize = sizeInBytes;
int unitIndex;
for (unitIndex = 0; unitIndex < SIZE_NAMES.length; unitIndex++) {
    if (displaySize < 1024) {
