Creates and restores compressed images of Linux EXT2, EXT3 and EXT4 partitions.

Instead of storing the complete partition, PiExt stores only the sectors currently used by the filesystem. The data is compressed on the fly using Zstandard (ZSTD).

The first image created in an image folder automatically becomes a Base Image. Further images are created as Differential Images based directly on the Base Image.
