columbia16 but it only gives me 20G of storage for images -
Unlike other Raspberry Pi 4 software, like INDIGO Sky, ASIAIR does not know how to expand the disk image on the fly.
The image was built for a 32 GB microSD card, and even if you use a 256 GB card, the partition will remain fixed at 32 GB.
Subtract the storage used by code and data, you end up today with about 20 GB of user storage.
You should be able to expand it on a computer that can read/write ext4 file format. However, be aware that after creating a 128 GB partition, burning the image into a microSD card could take well over an hour.
With other software, you basically burn a 10 GB partition in 5 minutes, and Rasperry Pi expands the partition the first time it is booted.
It may become worse in the future, since ASIAIR has already bloated quite a bit over the past two years.
