The XZ archive is extracted into a temporary working directory and repacked as 7Z. Everything happens in a directory that is removed afterwards even if the job crashes, so nothing is left behind on the server.
Settings this conversion runs with
| Source family | Single-file compression |
|---|---|
| Target family | Multi-file archive |
| Contents | Byte-identical after repacking |
What changes
- The XZ is decompressed to a temporary file and then packed as the single entry of a new 7Z archive.
