You will need to use an empty USB stick to transfer the files from your Mac or PC to the PROFILER for the first time. The USB stick should be pre-formatted with file system FAT32. When you connect the USB stick for the first time, the PROFILER will format it to ensure maximum reliability. Please be aware that formatting a USB stick will delete all the data on it! A USB stick that has been formatted by the PROFILER will contain the folders “Backups”, “OS update”, and "Shared".

Yes, of course you can use any USB stick, as Sollazzon so correctly says.

I thought the link was to show an example of a USB stick

I would never pay € 50 for "studio" profiles I know nothing about .......

Cheers !
