Hi,

as in some messages, there is not enough information to make an advice.


However, here?s one answer in the form of a question:

What is the size of the two respective(s) hard disk ?

Original application size:    1.4 MB. Hard drive size (in GB): 
Manipulated application size: 2 MB. Hard drive size (in GB):    


Last: a one byte SimpleText file takes less than 1KB in a floppy disk (either 
800 KB or 1.4 MB). If you copy that floppy... Err.
that file to a 40 MB hard drive it will take more rooms in the hard drive. The 
used room increase "proportionally" to the hard disk
drive !


Now you know the difference between real size (in Bytes) and logicial size (in 
KB, MB and eventually in GB).

HTH,


Emile

_____________________________________________________________________________
If you copy that fancy 1 byte SimpleText file from that floppy to a hard disk
(whatever can be its size)..., its real size will still be 1 Byte ! but its
logical size increase more and more depending on the hard disk size !

In MacOS 9 and lower, the GetInfo window show both values, but since the 
logical value is displayed first, usually people read only
that value and forget the real size (the one in Bytes).

Don?t be fooled, the logical size is unavailable for other storage purposes... 
HFS+ add an interesting compromise, but this is
another story (storage optimization vs speed I/O)

ok I have an application duplicate.. One copy is original and one is
manipulated.. the original is 1.4 Mb and the manipulated is 2mb how did the
programmer do this? I opened them in resorcerer and compared the two..
everything the same...
