And now, since I “installed” the new version of Ventoy, and since I’m pretty sure SUMo relies in part on crowd-sourcing, and since I did another SUMo run *after* updating Ventoy, *all* SUMo users who have Ventoy on board will likely be informed of the new version on the next run. It’s rare that gHacks beats SUMo (Software Update Monitor) to the punch in informing me of available updates, but this article on Ventoy was one of those exceptions. Select Options > Non-destructive Install to install Ventoy on the device without the deletion of existing data. The first partition must have a drive letter.It's also OK if you already has enough unused space (32MB+) after the 1st partition.(Then we don't need to shrink the 1st partition anymore). The non-destructive shrink need some free space.For FAT32 you can do a non-destructive convert to NTFS firstly. This is because Windows APIs only support to shrink NTFS.The first partition needs to be NTFS, not another file system.In Windows, the 1st partition is start at 1MB by default. Both MBR and GPT must meet this requirement to match Ventoy's disk layout.For GPT partition style, if there already exist 128 partitions in your disk, then it can not do non-destructive installation.For MBR partition style, if there already exist 4 partitions in your disk, then it can not do non-destructive installation.

The USB device needs to have space for a new partition that Ventoy requires.The developer of Ventoy describes the process on this docs page on the website. It is recommended that you back up the data before you use it at this stage. Support for the feature is experimental at this stage.
