3 partitions - would this work

[bbertrand007]

Press F2, you can browser other partitions in your computer and select ISO files to boot.
Not only the partition 3 in the USB reserved space but also other partitions (e.g. partitions in your local disk/HDD).

Thanks.  One last question - is the GAP also called "Hidden Track 0"?  If I do a Ventoy Update, is this information re-written (just curious)?  Thanks and best wishes on Ventoy.  I am a fellow developer (not on PC platform) so I recognize good software!!!
