Bzip2 had its era of packing source releases and backups tighter than gzip could, and .tar.bz2 files from that era still circulate. Opening one on an ordinary desktop takes conversion: the bzip2 layer is decompressed, the tar inside unpacked, and a plain ZIP built from the contents with structure intact. Modern machines then treat it as native. The decompression is slower than gzip's by the format's nature, and all of it happens locally.

Questions

Why does extraction take a moment?

Bzip2 trades speed for ratio in both directions; decompressing is honest work. The progress bar tells the truth meanwhile.

Is a .tar.bz2 handled fully?

Yes, both layers: decompressed, unpacked, rebuilt as one ZIP.

Where does this run?
