Yes, that?s why I have the other one at home. The reason I copy the launcher is that I now have a complete backup of the original 128 from the T3. The launcher is a copy of all the programs that are stored on the card (with only shortcuts on the T3). I often add or remove programs so the launcher file on the card changes with each add or subtract. Restore only restores what files were on the T3 at the time of the last backup. It does not restore what was already on the card, and what is in Flash. Of I lose the card and or backup card (64), I still have a total replacement.
In other words, on card A (128mb are a complete backup of the T3, and all the programs (163) resident on the card with only shortcuts on the T3. On card B (64mb) is only a complete backup of the T3. On card C (128mb) is a complete backup of the T3 AND a complete copy (Launcher file) of all the programs resident on the card normally in the T3. I can lose (or whatever) the T3, the backup card in the case, and still be in business. If the T3 goes out, I have the backup card. If it is lost or stolen or destroyed, I still have Card C to both restore and have the programs. If the T3 is destroyed or lost, All the programs in Flash will be lost except for the ROM backup on the A and C cards. I think I am protected for almost any contingency.
