Ventoy Persistence full - unable to login

[Neo]

Hi

I have ubuntu on ventoy with 4 GB persistence.

While installing software received an error that persistence space is full.

Now, i am unable to login there!

Is it possible to free-up persistence space using ventoy tools?

Also, tried adding additional persistence, but that seems to be unrelated to earlier one.

Can i add 16 GB to original persistence so that entire space is available to ubuntu as one, if yes then how?

Thanks
Neo
