Now we'll start tearing apart the zon file from the top down.
With the zon file open in Hex Editor, click the very 1st byte in the file,
click on edit then click Block mark.
We know 0A is the start of a new chunk so click on the 00 BEFORE the 0A.
Again click edit, Block mark and you should see this.
Click edit, select Clipboard, then Copy as hex string.
Now we open another Hex Editor.
Same one your using now just another instance of it.
Click on the 1st empty byte in this second Editor,
Click edit, select Clipboard, then Paste as hex string.
Save this as headerz.bin then close this second copy.
Back to the main part shown above,
click edit, select Block delete, and save the file.
We now have the header saved for later use and our zon file
is smaller and easier to work with.
