Code Snippet:

//Format file byte size
function FormatByteSize(const bytes: Longint): string;
const
B = 1; //byte
KB = 1024 * B; //kilobyte
MB = 1024 * KB; //megabyte
GB = 1024 * MB; //gigabyte
begin
if bytes > GB then
result := FormatFloat('#.## GB', bytes / GB)
else
if bytes > MB then
result := FormatFloat('#.## MB', bytes / MB)
else
if bytes > KB then
result := FormatFloat('#.## KB', bytes / KB)
else
result := FormatFloat('#.## bytes', bytes) ;
end;
