PTF Download

[Jerry Adams <jerry@xxxxxxxxxxxxxxx>]

I usually get my PTF's (CUME, Groups, etc.) from Fix Central via FTP.  
Originally I downloaded them to my PC and cut CD's.  Now I download 
straight to the image catalogue and cut out the middle man.

Part of the download is a text file with the byte count of each image.  
The accompanying text says "The byte count for the PTF file is exact 
since the transfer is done in binary."  But every time I look at the 
downloaded images in Windows Explorer the size is invariably smaller 
than what the text specifies.

I always go along blithely (blindly?) and install the PTF's.  Never had 
a (known) problem, but I was just wondering why the counts differ.  If 
Windows Explorer is reporting the wrong size, should I be using 
something else to check out the image sizes?
