Can I save my headers to continue working on them
Yes, you can. On the main Toolbar, the XHeader software
has a button named “Save XHF".
By clicking on the "Save XHF" button you can save the
current header graphic as a XHF file, so you can continue working on it at a later date.
You can achieve the same result by selecting the "Save
XHF" option from the File menu.
