Jos, AT Least, somebody with open mind, yes theoretically if no process have writed the sector of packed file it can be restored. I found the next code on my old downloads, its called unzap, it supposed to recover all zapped records, i was testing it but something is wrong.
I put this code here, i don't know who is the owner but, i'm sure it was totally free when i found it.
Take a look Jos:
*Hay veces que incluso despues de un ZAP, ;
se puede recuperar los registros, solo
*funciona si no se han escrito datos ;
encima de esos registros.

*Ussage:
*ZAP
*=UNZAP(47) && restore 47 records
