filesize

Is there any easy way to create a class that uses IFormatProvider that writes out a user-friendly file-size?

public static string GetFileSizeString(string filePath)
{
    FileInfo info = new FileInfo(@"c:\windows\notepad.exe");
    long size = info.Length;
    string sizeString = size.ToString(FileSizeFormatProvider); // This is where the class does its magic...
}

It should result in strings formatted something like "2,5 MB", "3,9 GB", "670 bytes" and so on.

All XSLT editors I've tried till now add tab or space characters to the XSLT to indent it for formatting.
