U3 Validation

[Malte Brill]

Hi Derek,

I also had that error when I validated drops for U3. Talking to  
Claudio of U3 it turned out I had to fiddle a bit with the  
manifest.u3i file inside the .u3p packackage. This package is  
basically a .zip folder. You can change the extension to .zip, search  
for the manifest file inside and open it with a text editor.

You need to make a change to the <options> element.


<options>
<!-- Defines the minimal (estimated) space required for the
application. -->
<minFreeSpace>number of MBs required</minFreeSpace>
<upgrade appData="add" deviceExec="overwrite"/>
</options>


The formula to calculate the number of MBs is:

U3P File Size + Uncompressed Size of DEVICE and DATA folder + 12%  
overhead.


Save the manifest file and change the extension of the package back  
to .u3p


Hope that helps,

Malte
