Glad you got it amos1. But 1.13GB? A typo?

@dasil
Mate that's got me beat. copydir works fine for me. I've got an otherwise healthy 1490 with a flaky USB socket and i've dumped the entire nuvi to a microSD, as well as individual folders. I've also deleted individual files on 0: and copied files 0: to 1: and 1: to 0: using the conventional command with ldr.bin in 0972 folder. If you have a bricked nuvi with cure fw on board the conventional sd method won't work of course.

I posted in this thread about a 1390 i bricked intentionally to test kunix's modded boot RGN method being used by amos1 and flashing worked fine for me using updater.exe to successfully dump NV and also to copy/delete files. i don't remember trying copydir on it bricked though but can't see why it wouldn't work. amos1 has used it to copy his GPX folder.
