By default, the TFTP protocol has no command to ask for the size of the file. To work around the problem, the client can load the file a few bytes at a time just to calculate the size. Once the size is known, the allocation is done and the file can be downloaded for real. The ATFTP adds the support to ask for the file size, therefore you save one download of the file. Note that elilo has the same thing when it downloads any file from the network. -- -Stephane
