ARJ at a glance
ARJ
Convert to ARJ when handling preserved DOS or early Windows archive inventories, especially multi-part historical distributions that downstream tooling still expects.
In most cases the practical task is to extract ARJ content and normalize it into ZIP, 7Z, or TAR variants for future use.
Choose ARJ only when legacy compatibility is a hard requirement.
TAR.ZST at a glance
TAR.ZST
Convert to tar.zst when you want a filesystem-preserving archive with modern compression performance.
It is ideal for backups, package artifacts, large project exports, and internal or public technical distributions where both throughput and compactness matter.
It is often the best modern default when you control the receiving environment and can assume zstd-capable tooling.
