function getReadableFileSizeString(fileSizeInBytes, decimalPlacer=1) {
// for more concise solutions see: https://stackoverflow.com/questions/10420352/converting-file-size-in-bytes-to-human-readable-string
var i = 0;
var scale = 1024;
var byteUnits = [' B', ' KiB', ' MiB', ' GiB', ' TiB', 'PiB', 'EiB', 'ZiB', 'YiB'];
while (fileSizeInBytes >= scale) {
fileSizeInBytes = fileSizeInBytes / scale;
i++;
