So, it's about importing and not storing nor restoring.
Normally, this formatting isn't needed, USB flash drives are already preformatted with FAT32. You just need to plug the USB flash drive once into your PROFILER. If soft button 3 shows "USB Stick" onscreen, you are done. No formatting is needed anymore.
The terminology in the video is not precise. He is talking about "PROFILEs", but he seems to import Rig files. Files available in Rig packs, Rig Exchange and commerical offerings are normally complete Rigs which included a PROFILE. I try to clarify this, since theoretically somebody could share PROFILEs in the form factor of amp presets, cabinet presets or stack presets. These can also be imported from USB flash drive, but afterwards don't appear in your pool of Rigs, but in your pool of amp, cabinet, or stack presets.
The video then shows how to unzip and copy Rigs into the folder Shared on the USB flash drive and how to import from there. This should work.
If you afterwards don't find those Rigs, you are either not looking at the right place
- browse the pool of Rigs
- and set the View to "All Rigs", otherwise you might just see a fraction of the Rigs stored in your pool
or the files are currupted and no valid Rig files and consequently not imported
or the Rigs were stored with an OS version significantly younger than the OS installed on your PROFILER, so that your PROFIDLER doesn't accept those as valid Rig files.
If you cannot figure that out, open a support ticket and inlcude:
1. which OS is currently isntalled
2. an example of a file you try to import
3 a current backup of your PROFILER.
