I was afraid of that...I was hoping there was something I was missing...

The data is being written from another application to a binary file. I 
have isolated and confirmed that 4 bytes correspond to a certain number 
input (a maximum folder size is what the number means). I am reading the 
file and parsing it's information. I have every field working except for 
this max folder size.

It appears that my numbers for 50 were wrong in my original post, 
although with the logic you applied Ara my wishful thinking was still 
way off base.

Here is a sample of the first 50 rows of data. Each row signifies the # 
of Megabytes defined for max storage. Each column signifies a byte in 
the position they are in the file. The first column and the first row 
are labels in this email.

This is another numbers/patterns/algorithms things similar to what I 
posted a few weeks ago, but this time it appears slighly more difficult.

If anyone has the time, the patience and the know-how to make sense of 
this, any help would greatly be appreciated. If not then I will keep 
thinking about ways to attack this problem. Thanks in advance,

Zach
